essage

It is indeed my great pleasure that the Department of Mechanical Engineering is

conducting this International Conference on Mechanical Engineering Design. After it’s inception

in the year 2007 this is the second International Conference that is being conducted by our

department. Over the course of time this department has been able to contribute towards the

research and technical training for the students and faculty through various programs like

Workshops, Government funded Faculty Development Programs, Symposiums, Robotics,

Glider, Automotive and Design training. The previous conference was based on the ‘Energy and

Materials’, and this Conference is focusing on ‘Design and Manufacturing’. Thus the

Department is driving the motivation in all directions of engineering year by year. The

enthusiasm and feedback of the delegates who were part of the conferences were the real

success of the program. I hope this conference will be enjoyable, memorable and I believe it

will open to all the delegates a world of new thinking and understanding to the latest technical

innovations.

I wish all the faculties, scholars and students who have served the conference as

Conveners, Reviewers, Editors, Office bearers, Program Committee members, Technical

Committee members and Treasurer for their tireless work. Wish you all success.

essage

Design is the prolonged checking, pondering, and compromising on requirements which

are often quite contradictory until there appears - as the end product of numerous associations

of ideas, a network of ideas – “the design”. Right from the time the wheel w as invented, all the

things that man has created has a rationale behind it. Almost all the manmade objects that we

see around us have an engineering design component in it. While the spoon is a very basic

example, the complex artifacts that humans make today invariably involve engineering design.

The Worli Sea link in Mumbai, the fastest car in the world, the supersonic jets, smart phones,

the Burj Khalifa and the latest innovation in diagnostic medicine - all are examples of

engineering design at work. Thus, the prime purpose of engineering design is to apply scientific

knowledge to the solution of technical problems.

While engineers provide a technical solution, it is very important to understand that

engineering design implies a solution that is aesthetic as well. In other words, designers too are

involved to ensure that the end product is economical, ecofriendly and appeals to users.

essage

Since the ancient, Men have made design as a way to meet needs, by performing

process of experimentation, analysis of materials, configuration and ergonomics. Over the

years, this design improved and became important inventions such as cars, aircraft, spacecraft,

etc. Thus, the importance lies in applying creativity to a specific end while satisfying needs. The

design engineer needs not only to develop competence in their field but must also cultivate a

strong sense of responsibility and professional work ethic.

Design is an innovative and highly iterative process. Every manufactured product is agood designer’s manifestation of knowledge but still with an emotional input to the form,

appearance, packaging and marketing (art). To be 'design' or a 'design' the expression must be

creative. From smart phones to goal-line technology, from artificial hearts to re-usable

spacecraft, and from air capture devices addressing carbon emissions to mapping the human

genome, mechanical engineers are at the forefront of ground-breaking innovations which offer

unprecedented opportunities to further human understanding and enable global society to

become ever more advanced and sophisticated in its capabilities, and adventurous in itspossibilities.

TECHNICAL SESSION-IDESIGN – I

AB16513 Design and C – Leg Analysis of Leg Wheel Hybrid Hexapod Bot

S.Vasanth, M.Harikrishnan, K.Abbhivignesh, B.Karthikeyan, M.Vignesh

The conventional mobile robotic platforms which either uses wheels or legs are quite familiarand each one of them has its own advantages and disadvantages. The wheeled robot is

suitable for only plain and smooth terrain, whereas the legged robot can travel in any kind ofterrain but is comparatively slower than the wheeled robot. So, a hybrid of both wheeled andlegged platform would be quite suitable for any kind of terrain. The primary focus of this

project is to design and develop a leg wheel hybrid robotic platform with a concurrentengineering and mechatronics approach to produce results with optimised design metrics ateach and every stage of its development. This paper details the Finite Element Analysis (FEA)of the C – Legs which are used in the robot.

AB16614 Study on the Use of Boundary Characteristic Orthogonal Polynomials inDetermining the Fundamental Frequency of Rectangular Plates withBidirectional Linear Thickness Variation

Tanmay Gupta, Bhagat Kewlani, Kiran D.Mali

Free vibration of rectangular plates with linearly varying thickness is considered. Plates are

important structural components used in aircrafts, bridges etc. and hence for their safedesign, thorough vibration analysis is important. Many research and practical applicationsuse plates of variable thickness due to economical usage of the material and increased

strength. Vibration response of these types of plates is different from plates of uniformthickness, which makes their analysis critical. In this study, Boundary CharacteristicOrthogonal Polynomials (BCOPs) in one and two dimensions have been used to obtaindeflection shape function. The first member of the series is generated using the boundaryconditions, in this case all edges clamped, which satisfies both the geometric boundaryconditions and the natural boundary conditions. Gram Schmidt Orthogonalization for

polynomials is used to generate the higher members of the shape function which satisfy the

geometric boundary conditions only. Thickness variation considered for the plate is linear inboth x and y direction. Natural frequencies were obtained by using Rayleigh-Ritz method.

Natural frequencies were calculated by varying taper parameters for both directions andcompared with those obtained with the case of uniform thickness. Natural frequencies were

also found comparable with those obtained from Finite Element Analysis by using ANSYS .

AB16533 A Structural Dynamic Approach to Evaluate Modulus of Elasticity of CantileverBeam

K. Mohammed Haneefa , S. Girish, R.V. Ranganath, Biswarup Saikia

The modulus of elasticity is an important property of any structural member or machinecomponent. It has a vital role in designing the structural components or machine components

for their specific use. This paper discusses evaluation of modulus of elasticity of cantileverbeams made out of Self Compacting Concrete (SCC) using a structural dynamic approach – the free vibration test. The concept of free flexural vibration essentially involves setting up a

specimen (beam) into ‘free vibration’ by imparting an initial condition, such that the specimen vibrates in its fundamental natural frequency. The digital data were stored using anefficient data acquisition system (Daisy lab version 5 software) and processed using Fast

Fourier Transformation (FFT) (Acceleration v/s Time). The fundamental natural frequenciesthus obtained were used to evaluate dynamic modulus of elasticity of SCC specimens usingwell established basic equations of structural dynamics. The study revealed that the dynamicmodulus of elasticity for the cantilever beams were equal to the initial tangent modulusobtained by conventional compresso-meter method as per ASTM C 469-02. Moreover, the

free vibration tests exhibited high consistency and repeatability. This technique can be of potential use as Non-Destructive Testing (NDT) for monitoring the health of in situ structuresor machine components.

AB16536 Effect of Yield Stress on theBehavior of Rigid Zones during the Laminar Flow ofHerschel-Bulkley Fluid

Taibi Hadi , Messelmi Farid

The paper is devoted to study numerically the evolution of rigid zones that appear during the flow of Herschel-Bulkley fluid. For this aim, we consider a laminar flow of two Herschel- Bulkley fluids in a bounded domain, in order to determinate the effect of the yield stress on therigid zones behavior, to locate these solid cores, to plot and to propose a model that candescribe the relationship between the area of rigid zones and the yield stress.

AB16543 Design And Analysis Of Airfoil- Shaped Impeller Blades Of Centrifugal Pump

Parth Shah , Ashwin Ganesh M

This paper deals with a comparative study of the outlet pressure-energy between aconventional and normal blade impeller and an airfoil-shaped blade impeller of a centrifugal

pump. Although the volute casing is an important component along with an impeller, the present comparative analysis makes the volute casing redundant to the study, henceneglected. All centrifugal pumps are usually designed and manufactured using backward

swept blades with equal camber on the top and bottom sides. An increased camber on the top side is an ideal trait for a lift generating airfoil. The purpose is to implement the principle of

lift generation of airfoil for centrifugal pumps. As a result, a local suction side and pressure side can be visualized using CFX-post processor. The 3D analysis of such a centrifugal pump




19

impeller is designed in SOLIDWORKS® and analyzed using ANSYS® CFX. The

SST(Menter’s Shear Stress Transport) model is used as it combine both the k- ω and k- ε

turbulence models.

AB16554 Effect of cooling medium on fracture toughness of Roto moulded Product

PL. Ramkumar, D.M. Kulkarni, V.V.Chaudhari

In day-to-day life, usage of plastics is numerous. It offers variety of benefits compared toother materials in various sectors like house hold applications, agricultural industry, and

packaging, etc. There are numerous methods for processing plastics. These include: blowmoulding, injection moulding, rotational moulding, transfer moulding and thermoforming.

Rotational moulding is a competitive alternative to other plastic manufacturing process, sinceit offers designers an opportunity to achieve an economic production of stress free products.

Many products made by rotational moulding process using linear low density polyethylene(LLDPE) are widely used in outdoor applications such as boats, over head tanks, and carbody parts etc. In such applications, fracture properties are considered to be critical from thequality characterization point of view. Selection of appropriate cooling medium plays vitalrole to enhance the quality of rotomolded products. In this paper, an attempt has been madeto investigate the effect of cooling medium on fracture toughness of the rotationally moulded

products. Fracture tests are carried out on a compact tension (CT) test specimens preparedas per the ASTM D 6068 (2012). The tests are performed on a universal testing machine. R -curve method is used to determine the fracture toughness ( JIC ) of rotomoulded products.

From the experimental results it is found that rapid cooling method favours better fracture

toughness of rotomoulded products. Therefore, it is recommended to use faster cooling aidslike water cooling in rotational moulding process to achieve highest fracture toughness.

AB16555 Advanced Machines And Automation Techniques In Modern ConstructionPractice And Their Possible Use In India

Mahima S, Soumya K, Bahurudeen A, Haneefa MK, MahalingamB

Robotics and automation are playing very imperative role in the modern construction practiceto meet the challenges and expectation specifically in the infrastructural projects. Automation

is a tool for operating or controlling different stages of construction process usingmechanized and electronic devices or control systems to reduce the human intervention to aminimum. The implementation of these automation technologies has shown progressiveoutcomes compared to conventional methods. Moreover, considerable improvement inworking condition, reduction in accidents and significant increase in production have beenevidently observed in the recent construction projects as well as in the earlier research

studies. Although several countries have adopted automation in their construction projects,application of these techniques in India is limited to a greater extent due to lack of proper

guidelines and specifications. It is important to develop appropriate standards and guidelines for Indian construction sector. This paper reviews different automation techniques that are

currently used in many parts of the world and suggestions for their application in the Indianconstruction scenario are discussed in detail. Moreover, guidelines for efficient




20

implementation of automation techniques in India are highlighted in the paper.

AB16572 Generation of Coupler Curves for Planar Kinematic Chains Using QuadraticEquations

Harishankar Singh Yadav, Dr. Shubhashis Sanyal

Analysis of four bar kinematic chain for generation of its coupler curves and functions generation is well researched. However, limited amount of work is reported for higher linkmechanisms. In the present work an attempt has been made to propose a simple analyticalmethod to generate coupler curves of kinematic chains. Present method is based onidentifying the joint locations of all fixed and moving joint. Simultaneous equations ofquadratic nature are proposed for each and every moving links to provide dimensionalconstraints with respect to the fixed link. Computer program have been generated todetermine the positions of all moving joints, by solving these non linear simultaneous

equations. To plot the coupler curve of any point selected on particular moving link, use ofrelative angles between the joints has been done. Matlab – mathematical software has beenused to solve the non-linear simultaneous equations. Analysis of the cases referred arecarried out and coupler curves are generated for four bar mechanism, all five inversions of

six link mechanism (i.e.Watt-I, Watt-II, Stephenson-I, Stephenson-II and Stephenson-III), andeight link mechanism. Results obtained are reported.

AB16578 Effective Stiffness Behaviour of Sandwich Beams under Uncoupled Bending andTorsion Loadings

Hugo Miguel SILVA ,José Filipe MEIRELES

Sandwich geometries, mainly in the form of panels and beams, are commonly applied invarious transportation industries, such as aerospace, aeronautic and automotive. Sandwich

geometries represent important advantages in structural applications, namely high specific stiffness, low weight, and possibility of design optimization prior to manufacturing. The aim ofthis paper is to uncover the influence of the number of reinforcements (ribs), and of thethickness on the mechanical behavior of all-metal sandwich panels subjected to uncoupledbending and torsion loadings. In this study, four geometries are compared. The orientation ofthe reinforcements and the effect of transversal ribs are also considered in this study. It is

shown that the all the relations are non-linear, despite the elastic nature of the analysis in the Finite Element software ANSYS MECHANICAL APDL.

AB16634 Comparison of Collapse Load of Pipe Bends with Assumed and Actual CrossSections

T Christo michael , Patil Amol Diliprao, AR Veerappan

The finite element nonlinear limit analysis compares the four cross sections to include theeffect of ovality and thinning on collapse load of pipe bends when subjected to in-plane and

out-of-plane bending moments with and without internal pressure. The assumed cross sectionsnamely elliptic and semi-oval and the actual cross sections are compared with circular cross




21

sections. A new methodology is proposed to use actual cross section in the finite elementanalyses. The comparison reveals that the actual cross section produces a positive effect ofincreasing the collapse load for lower bend radii and the assumed cross

sections produces minimal effect and hence circular cross section may beassumed. For the highest bend radius, actual cross section is preferable as the percentdifference is higher than other cross sections for low pressures. In all the pipe bend modelsand loading, when the pressure is high, the effect of ovality is very less and hence circularcross section may be assumed.

AB16583 Vibration Based Piezoelectric Energy Harvesting

T S Shakthivel, Ramesh, Gupta Burela

Piezoelectric energy harvesting has applications in aircraft technology, where the piezoelectric patches are attached to the wings of the aircraft to convert the mechanical

vibrations into useful electrical energy, which further is used to power the sensors of Aircraft Health Monitoring System. In this article, the performance of vibration based piezoelectricenergy harvester (PEH) in a given frequency range is studied. A piezoelectric material thathas a maximum piezoelectric coefficient (PZT-G1195) is chosen to increase the effective

power output. The output power generated by the harvester due to transverse and longitudinalvibrations are compared. The final step involves designing an electric power conditioningcircuit to convert the Alternating Voltage harvested into Constant Voltage, making it suitable

for storage.

AB16841 Sliding wear analysis of a metallic coating on ABS plastic substrate

Shrutee Nigam , Saroj Kumar PatelSiba, Shankar Mahapatra

In the recent times efforts have been made to combine plastic and metal, and to bring forth a product that has the goodness of both. With metallization the plastic gains the properties likethermal conductivity, strength and hardness. Methods discovered are usually costly, complexand environment unfriendly. Metallization of plastics has opened the door for its use invarious fields such as electronic industry, textile industry and automotive industry. Metalliccoating are also desirable in providing finish on the items like cell phones and laptop cases.The electric arc spray approach has been used to deposit copper on the acrylonitrile-

butadiene-styrene (ABS). This work makes an extensive study to analyze the factors that are significantly affecting the wear nature of the deposited coating and to obtain an optimalcombination of process parameters that results in a coating which adherant enough and hasthe lowest wear rate.

AB16559 Improved Thermal Comfort Design In Textile Garments Using CFD Simulation

Atheequr Rahman C, Sethumadhavan R ,Abdul Muthalib M

Unlike commercial buildings, many textile garments buildings in India are designed for

natural or mechanical ventilation to fulfill thermal comfort without or with HVAC systems. Inhot weather, due to too many workers having worked at same time, the thermal conditions in

factory were so poor to affect production, especially for large factory. Therefore, it isimportant to study the ventilation conditions of textile garments buildings and to exploreeffective means to improve the ventilation design of textile garments buildings. This study wasconducted using Design Builder CFD software to improve the ventilation performance in one

floor of factory. The field study was carried to collect the actual data of boundary conditions for CFD simulation. In this study, four different scenarios systems were simulated, comparedand analyzed. Based on the simulation data, it is found that evaporative cooler with HVLS fanand exhaust on wall can help to improve the thermal comfort conditions most efficiently andeconomically. Air conditioned with the insulation wall also gives the thermal comfort with

required condition but the cost of the system is very high.

AB16629 Effect of a o / W ratio on fracture toughness parameter of extra deep drawn steelsheets: experimental and finite element studies

Vikas Chaudhari, D M Kulkarni

Fracture toughness parameter is significantly affected by specimen dimensions i.e. specimenthickness ( B ), width ( W ) and unbroken ligament length ( W -a o ) in elastic-plastic region.

Present study is about the third dimension of test specimen ( W -a o ). In order to investigateeffect of a o / W ratio on fracture toughness parameter, fracture test and finite-element (cohesive

zone model (CZM)) simulation tool are used. Fracture tests are carried out on extra deepdrawn (EDD) steel sheets using compact tension (CT) type specimens with different a o / W ratio (0.5, 0.525, 0.55 and 0.575). After successive experimental attempts, load droptechnique is used as a fracture criterion. Critical CTOD is used as a fracture toughness

parameter. An alternative constant traction separation law is used to account for maximumload and large load line displacements. Experimental findings as well as finite element studies

show that the critical CTOD decreases with a o /W ratio. It has been observed that as a o /Wratio increases, the location of plastic hinge shifts towards the crack tip (i.e. size of tensile

plastic zone reduces), which reduces fracture toughness. That is, the material is less resistantto crack growth for deeper cracks.

AB16640 Finite element analysis of particle impact on HVOF thermal spray coatingsubstrates

Vaibhav G Shelar

Lower flame temperature characteristics of high velocity oxygen fuel (HVOF) flame spray process favor several surface coating applications. HVOF coating is extremely complex toanalyze, since its properties and microstructure depend on numerous processing parameters.

Finite element analysis (FEA) is used in this paper to analyze the influence of particle heatand impact velocity on HVOF coating substrates. HVOF thermal spray coating conditions,emulating Tungsten Carbide Cobalt (WC-Co) particles and steel substrate were modeledusing ANSYS APDL. Droplets of different size were considered as particles in the numericalanalysis to study their impact on the substrate. Thermal and residual stress analysis was done




25

on both the particle and substrate during different stages of the high velocity impact process. Both rigid and soft conditions of the particle and substrate were simulated. Thermal stress ofboth the particle and substrate were found to increase rapidly very close to the impact

process. Smaller sized particles had higher plastic strain and stress when compared to larger sized particles. However, the residual stress and plastic strain of the substrate increased

when impacted by larger sized particles. Residual stress of both particle and substrate were found to be influenced by the impact and thermal stress of each other. Higher velocity of the flame spray showed improved plastic strain and stress on individual particles, which is amajor reason for the dense pattern of coating.

AB16661 Computational Investigation Of Icing Conditions On The Velocity Profiles Of ACommercial Aircraft

Satheesh T, J.BruceRalphin Rose

Icing is a challenging problem in the aerospace environment especially for inter-continentalairline operations. Existing anti-icing methods offer consistent performance against glazeicing problems however it compromises the fuel efficiency through by-pass bleed air. A

Numerical analysis for an airfoil with and without icing conditions is done to investigate thevelocity distribution around the commercial airplane wing. The supercritical airfoil isanalyzed in step by step ice accretion aspect under optimal velocity input about 175 m/s. The

surrounding temperature is maintained in the range of 273K to 243K as per FAR standards atvarious angles of attack. The airfoil is designed by DESIGN MODELER module exists in

ANSYS workbench and it is meshed with ICEMCFD. Subsequently, it is analyzed with the helpof a flow solver at various time steps of ice accretion to verify the dynamic pressure changesdue to rime icing. The iced airfoil produced realistic C L and C D variations for different ice

shapes against the clean wing configuration. The step by step ice accretion is summarized and

the roadmap for ice elimination through coating techniques is proposed.

AB16666 Numerical analysis of hydrodynamic journal bearing lubrication usingcomputational fluid dynamics and fluid structure approach

D Y Dhande , D W Pande

Now-a-days, journal bearings are subjected to severe loads and higher operating speedscausing generation of high hydrodynamic pressures which in turn deform the bearing shellthus modifying the lubricating film in the operating region. Hence, there is need for optimizedbearing performance parameter estimation considering the realistic change in lubricating

film along with less computational time. In this paper, response surface optimization modulecoupled with static structural and fluent, available in ANSYS© Workbench is used foranalysing the performance of the bearing. The Optimization is based on Response Surfaceevaluations. It has been observed that the computation time is considerably reduced. Thebearing is analyzed for various rotational speeds to obtain load carrying capacity and

pressure distribution. It is observed that the results are following the expected trend i.e. as speed increases the load carrying capacity as well as maximum pressure is increasing.

AB16783 Simulation Of Erosion Wear In Slurry Pipe Line Using CFD

Vikas Kannojiya, Satish Kumar, Mani Kanwar, S.K. Mohapatra

Erosion is a serious problem faced in many industries that includes the transport of sand andwater slurry in slurry pipe line. This paper emphasizes on the investigation of erosion on amild steel straight pipe at different parameters including fluid velocity, particle size andconcentration. The fluid velocity is selected in the range of 2.5-10 m/s using computational

fluid dynamics code ANSYS-CFX. Sand particle within the size range of 100-400 µm size andconcentration 5%-15% are used in this study. An Euler-Lagrange approach is used to solvethe multiphase flow phenomenon. A horizontal pipe of diameter 100 mm and length 1 m (10

times of diameter) is considered for the study. The stochastic model of Sommerfeld will beused to account the wall roughness of pipe. It is also observed that the erosion wear in the

pipeline strongly depends on fluid velocity, particle size and concentration.

AB16597 Design and Performance Optimization of Off-highway Diesel Engine withMechanical Fuel Injection Equipment for TIER-IV Emission Norms Applications

S.Karthikeyan , K.Annamalai, M.Sathyanandan

The small power diesel engines are most demanding product in Indian market for power genset and Tractor applications. But major task faced by engine manufactures all over theworld is to upgrade running engine designs with minimum and cost-effective modifications tomeet next level of emission norms. This saves the precious lead – time and investments. Inaddition simplicity of design has to be maintained as far as possible while improvingemissions. Further the basic desires of the end user in off-road market are good response,transient performance, better low end torque, best fuel efficiency and smooth operation of theengine besides best in class reliability. Additional requirements needed to sustain the marketwith higher power to weight ratio and increased life of the engine. Henceforth turbo chargingapplied to off road diesel engines is a promising solution for enhancing rated power, low endtorque, transient performance, better low-speed torque, optimized fuel efficiency anddownsizing diesel engines. A trade-off is required to match some conflicting issues, i.e.overall dimensions, cost, emissions control and performance in order to sustain. Future dieselengine emission standards will further restrict vehicle emissions, particularly nitrogen oxides.

In the present work, a 1.7L, 2 cylinder in-line naturally aspirated diesel engine withmechanical fuel injection pump for off-road application is upgraded to satisfy all the needs ofthe market. Design up-gradation of this engine for Tier 4 is made with minimal designchanges by optimal combinations of fuel injection equipment. This includes properoptimization of performance with improvements in nozzle geometry, change in injector end

pressure. But due to the increased fuel flow rates for improving the engine performance aswell as emission reduction, there is requirement for increased air flow also. Henceforth in this

study air flow rate is simulated and discussed for selection of turbocharger and Intercooler.

Further elaborate design and analysis study is also done on cooled exhaust gas recircul ation system for exhaust gas cooling efficiency, as well as Diesel Oxidation catalyst (DOC),Selective catalytic Reduction (SCR)/Lean NOx Trap (LNT) substrate selection for reduced

pressure drop and maximum retention time for exhaust gas to achieve Tier 4 norms inturbocharged intercooled two cylinder engine.

AB16612 Propellant-Less Thrust Generation-A Review

Umang Singhal, Yash Pal, S. Murugesan

This paper introduces a concept of propellant-less microwave thruster for upper stage and space applications. The propellant-less microwave thruster works on classicalelectromagnetic theory, where the microwave radiations are converted to the electromagnetic

pressure that acts as axial thrust. In microwave thrusters, microwaves are radiated to a sealed conical cavity which follows the contour of the thrusters to produce pressure. Normally, there are three types of methods by which thrust can be produced without utilizingany propellant. Cannae Drive, EmDrive, and the Wrap Drive are mostly used. The first twoare based on the principle of microwave radiation, whereas the third method is just a conceptin various science fiction films. The EmDrive can produce a small amount of thrust, therefore;its application is limited to upper stage thruster, orbit/trajectory correction, and deep-spaceexploration. This paper provides an insight on the feasibility of EmDrive for spaceapplication by comparing its performance with ion propulsion system. The proposedmicrowave propulsion system has low system mass (typically in Kgs), produces high thrust (in




29

mN) and even has higher specific impulse (in years) which can outweigh the current ion propulsion system.

Ganesh M, Gaurav Ganti, Aushman Choudhury, Raja Sekhar Y

Waste disposal in remote areas is a hurdle due to lack of active dumping space. Besides,improper dumping of waste on empty land can have a detrimental impact on the environment.

Incineration of waste using thermal incineration (using a solar concentrator) can be utilized for mobile incineration devices to dispose of hazardous waste effectively with a limited space.The design and mobility of the solar dish for this purpose is one of the most importantconsiderations. The modeling of the solar dish was performed on SOLIDWORKS® with

APEX® for optical simulation. The simulation results showed a linear variation of fluxcoating to enable a more comprehensive cost benefit analysis for the design. The simulationwas also used to check whether the required flux at focus (to achieve ignition) was achieved.

Further work is required to validate the results.

Emerald Ninolin, Godson Asirvatham Lazarus, Ramachandran

The thermal performance of a compact loop heat pipe is fabricated and tested for differentheat inputs ranging from 30 W to 500 W using water and silver-water nanofluid with lowvolume concentrations of silver nanoparticles (0.03% and 0.09%) in vertical orientation. A

flat square evaporator having a bottom area of 30 mm × 30 mm and a height of 15mm is usedin the present study. The effect of heat input on the thermal resistance, evaporation and

condensation heat transfer coefficient is experimentally investigated. The results showed thata reduction in the evaporator thermal resistance of 26.45% is achieved with 0.09 volume

percentage of silver nanoparticles when compared with that of water. Further anenhancement in the convective heat transfer coefficient of 25.23% has been observed with the

same volume concentration of silver nanoparticles. Addition of small amount of nanoparticlesenhanced the operating range of heat pipe beyond 500 W and without the occurrence of anydry out conditions. From the outcome of this study, it is concluded that the compact loop heat

pipe with flat square evaporator can be used for thermal control of electronic equipmentswith limited space.

Ramji V, Mukesh R, Inamul Hasan

This works centers on the design of a De Laval (convergent - Divergent) nozzle to acceleratethe flow to supersonic or hypersonic speeds and computational analysis of the same. Aninitial design of the nozzle is made from the method of characteristics. The coding was donein Matlab to obtain the contour of the divergent section for seven different exit Mach numbersviz. 2.5,3,3.5,4,4.5,5 and 5.5.To quantify variation in the minimum length of the nozzledivergent section with respect to the exit mach number, a throat of constant height(0.005m)and width (0.05m) was chosen for all the design. The area exit required for each

mach no varying from 1 to 5.5 was plotted using isentropic relations and was also used toverify the exit area of the nozzle for each of those mach numbers. An estimate of the exit




31

pressure ratio is obtained by using isentropic and normal shock relations. With this exit pressure ratio, a more refined verification is done by computational analysis using ANSYS Fluent software for a contour nozzle with exit Mach number 5.5. The spalart Allmaras and k-epsilon model were used for turbulence modeling.

Hugo Miguel Silva, José Filipe Meireles

Several types of internally reinforced thin-walled beams are subjected to a feasibilityevaluation of its mechanical behavior for industrial applications. The adapting of alreadyexisting efficient sandwich geometries to hollow-box beams of larger dimensions may reveal

promising results. Novel types of sandwich beams under bending and torsion uncoupledloadings are studied in terms of stiffness behavior in static analysis. For the analysis of the

solutions, the models are built using the Finite Element Method (FEM) software ANSYS Mechanical APDL. The feasibility of the novel beams was determined by the comparison ofthe stiffness behavior of the novel hollow-box beams with conventional hollow-box beams. Anefficiency parameter was defined in order to determine the feasibility. It is found that thenovel geometries represent an excellent improvement under bending loadings, better than

under torsion loadings. Nevertheless, for bending and torsion combined loadings, if bendingloads are predominant, the beams can still be interesting for some applications, in particularthose with mobile parts.

Laxmikant S. DhamanD Mangesh B. Chaudhari

Bearing is an important component of almost every mechanical system used in industrialenvironment. Hence the defect in bearing must be detected in advance to avoid catastrophic

failure. This paper aims to diagnose the defect in bearing automatically using machineintelligence. A condition monitoring setup is designed for analyzing the defects in outer race,inner race and ball of bearing. MATLAB is used for feature extraction and neural network is




33

used for diagnosis. It is found that the amplitude at defect frequencies may not always clearlyindicate the increment; hence statistical analysis of bearing signature is a better alternative.The work presents an experimental investigation carried out on an experimental set-up for the

study of bearing fault at same angular speed. This paper proposes an approach of damagedetection in which defects in bearing are accurately analysed using vibration signal and

Divya Zindani, Apurba Kumar Roy, Kaushik Kumar

Mixed flow pumps applications have been exploited in a large number of diversified fields ofengineering. They find applications as an important component in waste water treatment

systems, power stations, irrigation systems etc. User requirements make these pumps to workvery close to the functioning requirements and therefore under these conditions the vibrations

are bound to occur in different moving components of the pump. It would be difficult toanalyse the pump vibrations, considering the pump as a single system. Analysing vibrations indifferent moving components of the pump will not only be easier but also will aid in reducingthe vibrations at the microscopic level. As a subject of the present paper, the mixed flow pumpimpeller blade has been designed using sparingly used yet accurate mean stream line theory.

Modal analysis of the pump blade has been carried out at different modes of frequency. Totaldeformation for different modes of frequencies has also been determined. Stainless steel hasbeen used as the construction material of the impeller blade.

Ben Antony Johnson, Christo Michael

This study investigates the theoretical basis of the generation and geometry of the cylindrical

worms with convex-concave surface. The work deals with generation of a CAD model of theconvex-concave profile worms and determining the contact stresses and bending stresses forthe teeth in meshing of worm gear pair by using Finite Element Method and comparing the

structural efficiency of the convex-concave profile gears with the ZK worms.The advantage ofthe convex-concave type worm gear drives is the improved conditions of lubrication which isachieved due to the favorable shape of contact lines between the worm and the worm-gear

surfaces. The CAD model of the worm-gear pair is developed using Solidworks. The effect ofcontact stresses and bending stresses are found by applying Finite Element Analysis in

AB16671 Prediction of Workpiece Elastic Deformation using FEM based Contact Analysis

F Michael Thomas Rex, D Ravindran, N Lenin

The proper selection of fixtures and its locations is necessary to avoid the dimensional and form inaccuracies that are developed due to elastic deformation of the workpiece duringmachining. Hence, it is necessary to predict the elastic deformation of the workpiece withhigher precision in order to reduce the above inaccuracies. In the present work, a Finite

Element Method (FEM) based 3D contact analysis has been proposed to evaluate the elasticdeformation under the influence of fixtures and machining forces. A new concept of pre-

stressed harmonic analysis has been introduced in order to simulate the machining forces.The contact area of the locators has been considered using contact elements and the clamping

forces as point forces. The model for the analysis is developed in ANSYS environment with suitable elements. The natural frequency of the workpiece - fixture system is predicted andensured that the resonance condition is averted during machining. The effect of materialremoval has also been considered in the analysis in view of obtaining more accurate andrealistic results. It is inferred from the results that the elastic deformation increases due to

stiffness reduction during machining. It is possible to optimize the location of clamps andlocators under the influence of machining forces, the above analysis is suggested.

AB16694 Design of Reverse Flow Blockage Device for Reactor Coolant Pumps

Aravindan S, Bhagwana Ram Manda, Sreedharan K.V, Athmalingam.S,Balasubramaniyan V

Future Sodium cooled Fast Reactors (SFR) in India, are being designed with 3 ReactorCoolant Pumps (RCP). Reactor Coolant Pumps (RCP) are used in pumping the coolant fluidthrough the reactor core. As the RCPs are operating in parallel, failure of one pump willresult in a significant portion of the pumped coolant to bypass the core via tripped RCP. Thus,the reactor has to be shut down and the tripped RCP has to be replaced, which results indown time. Operation of reactor with only two RCP (2/3 mode) will supplement the power

generation. Henceforth, if the flow path through the tripped RCP is made highly resistant ascompared to the core, then eventually, flow from the two operating RCPs will go throughreactor core. Such a flow blocking/resisting arrangement can also provide the flexibilityduring reactor startup. A cylindrical shell is designed for closing the suction passage of the

pump and the shell is raised or lowered from above the roof slab with the help of tie-rods. The

cylindrical shell (sleeve shell) is designed to withstand water hammer shock due toinadvertent sudden closure of the suction passage. To determine the shell thickness, pump performance curves are developed based on reactor operating conditions. The sleeve shellwill not be able to perfectly close the suction passage as space is required for movement of

sleeve shell over the pump shell, thus a study is performed on incorporating a labyrinth tominimize the leakage.

AB16627 Passenger Comfort Analysis in an Automotive Considering a Suspension

with a Magneto-rheological (MR) Damper

Soujanya R B, Dr. Davidson jabaseelan D, Dr. S Kannan

Passenger’s comfort in moving vehicles depends on the quality of the ride. The major cause ofdiscomfort is the vibration transmitted to passengers and road irregularities. These are the main

source of vibration in a vehicle. For a comfortable ride on a vehicle, vibration must stay within prescribed standards. In the paper, an attempt was made to show that, the vibrations can be limited tothese boundaries as per standards with the use of magneto-rheological (MR) dampers. Magneto-

Rheological (MR) dampers are semi-active control devices that use MR fluids to produce controllabledamping force. They potentially offer highly reliable operation. Due to this MR dampers are known to

exhibit nonlinear behaviour. Multi body dynamic studies were done to study the response of the system. Since, in the assessment of comfort, only the acceleration of the sprung mass plays a key role,a quarter car models was preferred in this work. But extensions can be done to half car model. In this

paper, when passive damping (viscous damping) was applied at natural frequency of 1.012Hz, theresponse of damping was observed after 10s and the acceleration was 6m/s 2. Then, when MR damperas employed as the magnetic force increases, the response of the damping was better than the passivedamping [At 1.2A it comes down to 0.55m/s2, and the vibration gets dampened after 1.75s]. Hence,

from this study it is concluded that the MR damper can be employed in automobile for better ridecomfort.

AB16658 Designing of a Balanced Opposed Piston Engine

Sunil S. Hebbalkar, Kaushik kumar

An internal combustion engine with opposed piston engine (OPE) develops higher powerdensity than any other conventional internal combustion engine by virtue of its design. A Two

stroke OPE gives two power stroke within 360 0 of crank revolution which indicates the higher power density. But this extra power also results in large amount of forces gets transmitted toboth the crankshaft amounting to large unbalance in the engine. Hence for a smoother andnoise free performance, engine should be dynamically balanced. So balancing is one of themain criteria for better performance. In this paper the dynamic analysis was performed byvarying the linkage dimensions of OPE for balance OPE. The analytical calculation of inertia

forces and dimensions for linkages has been compared with software based results, dependingon pressure crank angle plot for two stroke engine.

Aravind Krishnan , Sanat K Sampat, Hemanth Vinod, M Suresh Kumar, Aswin BabuPK

Design of braking system is an important phase in the development of an automobile. Duringbraking, disc brakes accumulates heat energy and high thermal gradients which leads to




37

reduced functionality. This heat has to be dissipated for efficient functioning of brakes.Various designs for brake disc rotors have been developed in the past. In this paper, a noveldesign for brake is developed using SolidWorks tool . This model aims at maximum dissipationof heat by increasing surface area. A thermal flux analysis of the new model is done toconfirm this achievement. A comparative study of other designs of ventilated discs and a

plane rotor disc is also done. The calculation and verification of braking force is followed indesigning the disc rotor. The main objective is to generate more braking force so as tomaximize efficiency. The analyses are done in ANSYS to study and understand the heat fluxand temperature that are formed in the disc rotor.

P.Sabarish Kumar , S.Ashwin Kannan, A.Sathish Kumar, K.Arun Vasantha Geethan

In this study, for the first time analysis of a low heat rejection engine was carried out alongwith the addition of oxidation inhibitors. If the combustion chamber components of the engine

such as piston, cylinder head, and inlet and outlet valves are insulated with a thermal barriermaterial, then the engine will be referred as low heat rejection engine. In this study yttria

stabilized zirconia was coated on the combustion chamber components for a thickness ofabout 150 microns. Then the analysis of performance parameters such as brake thermalefficiency and specific fuel consumption and emission characteristics such as emission ofcarbon monoxide, hydrocarbon and nitrogen oxide was carried out in single cylinder four

stroke diesel engine with electrical loading using diesel and pongamia methyl ester as the fuels. The major problem associated with the usage of biodiesels and low heat rejectionengine is the increased NO X emission than the normal engine operated with the diesel. This

problem has been overcome by the usage of oxidation inhibitors such as ethyl hexyl nitrate(EHN), tert-butyl hydroquinone (TBHQ). The results showed that addition of oxidationinhibitors leads to increase in brake thermal efficiency, reduced specific fuel consumption andreduced NO X emission.

It wasexperimentally found that by adding n-butyl alcohol to neat jatropha biodiesel, significantreduction in viscosity was observed. In addition, break thermal efficiency was increased by0.8 % due to improved atomization of the blends. Further, brake specific fuel and exhaust gastemperature was further reduced due to lower viscosity and improved combustion rate withaddition of n-butyl alcohol to jatropha biodiesel.

D. Yuvarajan, R. Surendran, V. Vinoth Kumar

In this study, the outcome of adding n-butyl alcohol to jatropha methyl ester on the emissionscharacteristics of compression ignition engines is investigated. Single cylinder diesel enginewas fuelled with n-butyl alcohol / jatropha methyl ester blends. The doping volume of n-butylalcohol to jatropha methyl ester blends was in the range of 10, 20 and 30%. Emission

parameters such as Hydro carbon (HC), Carbon monoxide (CO), Nitrogen oxides (NOX) andSmoke emissions were examined at different load conditions. The engine speed wasmaintained constant throughout the trail. This work resulted in a significant reduction inreduction in all the emissions. Addition of n-butyl alcohol as additive improves the rate ofcombustion, mixing and vaporization of the blends with air and reduces the emissionsassociated with it. The other benefit of this work is that the fuel can be used in the existingengine with any modification. This also results that the addition of n-butyl alcohol to jatrophamethyl ester reduces the emissions associated with it. Further, no damage to enginecomponents was observed during the trail.

In order to reduce the need of petroleum fuels, the prospect of finding the alternative fuel is a primary goal. This work deals with the cause of mustard oil as a possible alternative. The physical and chemical properties of mustard oil are investigated. Using the gaschromatography, the composition of mustard oil is checked. Transesterification process isused for converting the mustard oil into biodiesel. Biodiesel thus formed is converted into bio

fuel by the addition of an oxygenated additive (methanol). The current experiment is performed by varying the compression ratio by 16, 17 and 18 using bio fuel which comprisesof 80% of mustard oil biodiesel and 20% of methanol in the diesel engine. Emission aspectsof bio fuel are investigated. From this experiment it is observed that, by increasing thecompression ratio CO and smoke emissions were slightly reduced, whereas HC emission is

significantly reduced. However, the emissions of NOx were found to be on higher side.

Battery management is essential for achieving desired performance and life for a particularbattery pack used for high / low rate applications such as electric, hybrid electric vehicles and

solar photo voltaic applications respectively. These cells/ batteries must be thermallymanaged in addition to the electrically controlled for the said applications. The major failuresoccurring due to temperature effect includes failure of the battery due to sulphation as aresult of increase in temperature and also insufficient solar insulation to charge the cell /battery. The life of cell / battery is declined by order of one magnitude per ten degree rise inambient temperature which leads to drying out of electrolyte in valve regulated lead-acidbattery and corrosion of grids. To design battery pack management systems, the designers

need to know the thermal characteristics of cell/ battery. This includes heat capacity of cell,modules, temperature distribution and heat generation in the cell / battery under various

S. Ravikumar, H.Kanagasabapathy, V. Muralidharan, S. Giftlin

Belt conveyor is primarily utilized for transportation of material from one location to another. Belt conveyor has high load carrying capacity, large length of conveying path, simple design,easy maintenance and high reliability of operation. Belt Conveyor system is typically used inconveying lakhs of tons of material per annum in core mechanical industries. They areextensively employed in ports, coal, metallurgy, mine, power plants and process industries.Training Carrying Idlers (TCI) are installed between the normal idlers to adjust thetransverse displacement caused by uneven loading, wet condition of bottom of belt side andbad training of conveyor belt. When the carrying belt moves against the guide rollers oneither side, owing to difference of friction force between both sides, the upper stand is

swiveled to center the belt. Then zigzag movement and abnormal damage of belt can beefficiently prevented by training idlers(TCI).Since TCI is found to be critical in belt conveyor

systems, it becomes necessary to oversee its smooth functioning. To make certain this,

condition monitoring of training carrying idlers (TCI) needs to be carried out which basically forms a classification problem. Training carrying idlers consists of main components such asbearing, axis shaft. The TCI is analyzed with the following cases such as TCI running at goodcondition (Good), TCI with bearing fault (BF), TCI with shaft fault (SF), TCI with shaft andbearing fault (SF &BF). A prototype investigational setup has been designed and fabricated,the vibration signals are acquired from the setup for different conditions of Training carryingidlers (TCI), followed by feature extraction and classification has been performed by decisiontree algorithms. Effectual Classification of faults in the Training carrying idlers by decisionalgorithm shows a rational performance in detecting faults in Training carrying idlers.

There may be several feasible sequences of assembly operations for assembling a mechanical product. Requirement of fixtures for each assembly sequence are different and hence theassembly lead time. Assembly Sequence Planning (ASP) is the activity of finding sequence(s)of assembly operations which has improved productivity and reduced lead time. Generating

such suitable assembly sequence(s) have always been a challenging research area becauseevery product is special in terms of its design characteristics. Significant level of automation

Design, Development and Electromagnetic Analysis of a Linear SwitchedReluctance Motor (LSRM) for Automatic Door Systems of Railway Carriages

V. Ganesh Sampath, K. Abhishek, N. C. Lenin

Day in, day out millions of people all around the world use public transportation systems.Within a metropolis, local rail transport is usually the only cheap and efficient way to get

from one place to another. This is making new demands on the rail -bound mass transit. Thedoor system needs to be robust, reliable, maintainable, safe and unaffected by theenvironment in order to guarantee an efficient train service. Because of round the clockoperation of these trains, it is difficult to maintain the door systems regularly. They also get

exposed to harsh environment like rain, sunlight and rough handling which may lead tomalfunction. Safety is a very important constraint in any mass transit system and anymalfunction in the door system can lead to severe mishap. Considering all the aboveconstraints, we are proposing Linear switched reluctance motor (LSRM) based door systems

for railway carriages. The phase independent nature of LSRM makes it the best choice fordoor systems application as it can be made to operate even if any phase fails to work. This

paper presents a clear design guide for a longitudinal flux single sided LSRM. The design parameters have been verified using two dimensional finite element analysis (2D-FEA). Finally a prototype has been built and tested. Test results imply the features of LSRM thatmake it a strong candidate for door systems of railway carriages.

AB16570 Geriatric walk assist robot – Design, analysis and implementation of a modularlower limb exoskeleton robot

Karthikeyan P, Satheesh Kumar G, Ajin M

Among the problems of major concern faced by the geriatric community the fore most isconsidered to be: “as we grow older it gets difficult to walk”. As they lose their strength towithstand their weight they become weak to walk on their own. Through this project a designis proposed for an assistive modular lower limb exoskeleton robot to enable aged people towalk on their own. The design is mainly based on the amplification of the pressure applied onthe thighs and ankles of the legs and these pressures are used to move the legs of the robotwhich support the legs of the user. Since the user is capable of generating a minimum

pressure on their own the working of the gait pattern is mainly based on the movement of kneeand ankle, and so only the knee and the ankle are considered in this design. Another reason isthat the major weight of the body acts on the knee and the foot while walking. The working ofthe robot is mainly based on the layered control algorithm embedded on the microcontrolleracting through the sensors and actuators. Pressure sensors are used to measure the applied

pressure and electrical actuators are used due to their lesser weight. Based on theexperimental results obtained with the working robot the design would be fine-tuned foroptimized performance.

Shrikant Gunjal, Shantanu Bihani

Roads are human tragedy. They involve high human suffering and monetary costs in terms

of untimely deaths, injuries and loss of potential income. Although we have taken manyinitiatives and are implementing various road safety improvement program the overall

situation is revealed by data is far from satisfactory. During the calendar year 2011, therewere close to 5 lakh road accidents in India which, resulted in more than 1.5 lakh person.These numbers translate intone road accident every minute, and one road accidentdeath every 4 minute. Unfortunately, more than half the victims are in economically activeage group of 25-65 years. The loss of the main bread winner can be catastrophic. Many ofcountries have curbed the menace of road accidents by adopting a multipronged approachto road safety. The government alone cannot tackle road safety problems. There is a need

for active involvement of all stake holders to promote policy reform and implementation ofroad safety measures and our project aims at the same. The traffic police play an important

role and are much efficient in handling such problems. They only need a support from the pedestrians and a new invention on how we can control the death figures. Our project gives the best alternative to deal with this type of problems. Addressing road safetyis comprehensive manner underscores the need to involve multiple agencies and sectorslike health, transport and police. The present study provides the magnitude and variousdimensions of road accidents in India.

AB16621 A Mechatronics Approach for Design of Multiview Image Acquisition Setup forScene Reconstruction with Single Camera

R. Senthilnathan , R. Anand, Roshan Suresh Kumar, Shreyansh Keseri

Conventional design approach is being actively replaced by concurrent design approach inthe context of interdisciplinary systems. The proposed research work intends to develop a

single moving camera based stereo vision system for scene reconstruction with the intrinsicadvantage of multi-directional fields of view. The conventional stereo vision setup uses two

stationary passive cameras to capture images of a scene from different vantage points. The proposed system imparts varying mechanical degrees of freedom motion for both the objectand the camera which aids in acquiring sequence of images which covers all the visibleregions of the object of interest. This gives better detail of the scene under consideration ascompared to the conventional two images based stereopsis. A mechatronics design approachhas been presented which carefully integrates various elements of the system such as themechanisms, actuators, sensors and the electronic controller. The paper clearly pin points thecues for the design of the mechanical system which are obtained from the requirements of thecomputer vision system. The relative pose between the camera and the scene is governed bythree independent degrees of freedom namely rotation angle for the object, tilt and workingdistance for the camera. The selection of the aforementioned parameters is decided by the

specifications such as field of view, size of the object and sensor and spatial resolution. The proposed design predicts the system to enjoy benefits of reduced cost and improved flexibilityin general.

V. Ganesh Sampath, K. Abhishek, N. C. Lenin

Linear induction motors (LIMs) are a very effective drive mechanism for actuation andtransportation systems. LIMs are capable of generating a non adhesive thrust force, providingboth propulsion and levitation forces and is hence considered as a promising propulsion

system [1]. LIMs are used in rapid transportation, baggage handling conveyors (beltconveyors), crane drives, theme park rides, induction pumps, impact extrusion machines,

flexible manufacturing systems etc. This is attributed to various advantages LIMs have suchas, high starting thrust, simple mechanical design and construction, alleviation of gearsbetween motor and the motion device, no backlash, small friction and sustainability for low

speed and high speed applications making LIM a strong candidate in applications with linearmotion. Force can be uniformly applied to the conveyor belt over a wide area without anymechanical contact by using LIMs to drive conveyor belts, making the drive independent of

frictional losses between the rollers and belt. This paper presents a design guide for alongitudinal flux single sided linear induction motor for conveyor application. The design

parameters have been verified using two dimensional finite element analysis (2D-FEA). Testresults imply the features of LIM that make it a strong candidate for simple conveyorapplications.

M.K.Loganathan,Priyom Goswami, Bedabrat Bhagawati

A method based on structural modelling is developed for failure evaluation and analysis ofmechatronics-based production systems. Majority of the elements in production systems aremechatronics-based, which includes various elements such as; electrical, electronic andmechanical. Each of these may have different failure types that may beinterdependence/interactive. The reliability of the system mainly depends on how well the

failures are taken care of during design stage. In general, individual failures are generalizedinto probable failure modes and early identification of these helps to reduce their probability.

However, consideration of failures and their interdependence / interactions will help toevaluate and analyse the failures of complicated systems in an efficient and effective mannerand increase the inherent system reliability. The system structure modeling helps in thisregard. Digraph model, in conjunction with matrix method, is employed for failure evaluationand analysis of a mechatronics-based production system based on its structure.

In this study, an effective method based on wavelet transform, for identification of damage onrotating shafts is proposed. The nodal displacement data of damaged rotor is processed toobtain wavelet coefficients to detect, localise and quantify damage severity. Because thewavelet coefficients are calculated with various scaled indices, local disturbances in the mode

shape data can be found out in the finer scales that are positioned at local disturbances. Inthe present work the displacement data are extracted from the MATLAB model at a particular




48

speed. Damage is represented as reduction in diameter of the shaft. The difference vectorsbetween damaged and undamaged shafts are used as input vectors for wavelet analysis. Themeasure of damage severity is estimated using a parameter formulated from the distributionof wavelet coefficients with respect to the scales. Diagnosis results for different damage cases

such as single and multiple damages are presented.

R.Manivel , Ebenezer Jacob, Satyan,Santosh

Produced natural gas stream from the reservoir is always saturated with water and one of the problems associated with its transmission especially in subsea pipeline is the formation ofhydrates. Hydrate formation in subsea pipelines is a major problem that arises due totemperature drop and other thermodynamic changes during production. The formation ofhydrates in subsea pipelines should be prevented effectively to guarantee that the pipeline

operates normally. Insulating subsea pipelines is essential to avoid possible hydrate formation .Heat transfer equation under steady state fluid flow as well as that for rate of heatloss was used to develop a simple model to analyze the insulation material required toeffectively prevent hydrate formation in a subsea pipeline. The results analysed using the

ANSYS software.

AB16713 An Effective Assistive Device

K Siraz, K Nikhel

The purpose of this study is to develop a simple back assistive device that generates sufficientassistive moment and is not subject to resistant forces while walking. It is widely known thatmany labor workers suffer from low back pain. To diminish their low back pain, developmentof a simple and practical back assistive device for use in the workplace is highlyrecommended. Some simple back assistive devices using elastic elements have been proposed.

However, under walking conditions, elastic tension generated by flexion of the hip joint exertsa resistant force against walking. Since the majority of physical workers in industries or other

fields have to walk while performing tasks, they require a back assistive device that has sufficient assistive moment in a bending forward posture and does not generate a resistant force while walking. The problem is how to decrease the undesirable resistant force fromelastic elements caused by walking, while maintaining a back-supporting property in bending

forward tasks. Focusing on the reciprocal motion of legs in walking, we devised a simple

mechanism by which elastic tension is diminished under walking conditions. On the otherhand, the tension of elastic elements is available in bending forward posture. Making use ofthe reciprocal motion of legs, two swing arms mounted on the device rotate synchronouslywith legs. Using this mechanism, elastic tension is almost completely eliminated underwalking conditions. The swing arms rotate in the same direction under walking condition, butthey cannot rotate in the opposite direction, so that elastic elements are stretched to producean assistive moment for the back in a bending forward posture. The device proved to beeffective in reducing undesirable tension in the lower belt under walking condition. Thetension of elastic elements caused by walking decreased to less than one-quarter comparedwith that of conventional back assistive devices.

AB16735 Design and development of a computer aided design model for preliminarydesign of drilling fluid for HP/HT wells

R. Sharma, S. V. Reddy

The era of easily producible oil and gas has been ended for quite some time and new oil and gas fields are slowly being discovered in low to high combinations HP/HT wells. This hasdemanded that new and novel drilling fluid designs be developed for low to high combinations

HP/HT wells. Primarily, the drilling fluid provides hydrostatic pressure to prevent formation fluids from entering into the well bore, keeps the drill bit cool and cleans it during drilling,carries drill cuttings, and suspends the drill cuttings while drilling is paused and when thedrilling assembly is brought in and out of the hole. Our firm belief is that a computer aideddesign model for preliminary design of the drilling fluid can be developed and it will lead to

optimal design for a particular set of requirements specifically to avoid formation damageand to limit corrosion. This work is planned jointly with the ONGC Limited and our plan is to




55

design and develop a computer aided design model for preliminary design of synthetic oilbased drilling fluid for HP/HT wells. We cover the pressure range of 13000 to 15000 psi, thetemperature range of 450 – 500 0F with the specific gravity varying from 2.0 to 2.5. In this

paper, we report the a computer aided design model for synthetic oil (i.e. a mixture of variousoils) based drilling fluid with selected and co-ordinated additives, e.g. suitable antioxidants

and emulsifiers as well as desired viscosifiers and fillers for desired rheological properties for drilling fluid uses. Our preliminary design results show that novel synthetic oil baseddrilling fluid that is optimized for particular conditions can be developed for particulartemperature and pressure ranges. And, in the optimization process critically important

parameters (i.e. high borehole stabilization, high penetration rates and high lubricity) can beoptimized for a specific well. We show that the synthetic oil based drilling fluid has inherent

strengths and they can be further improved with additives to achieve stable rheology and filtration control for extended periods of time and increased lubricity. Extending the samebasic configuration of the synthetic oil based drilling fluid we also briefly explore the idea ofaltering the design configuration to develop the ability to drill through most troublesome

shale formations due to their inherent inhibitive nature and temperature stability. Since, in HP/HT wells, only a small hydrostatic overbalance is tolerated due to the reduced marginbetween pore and fracture gradients, it is vital that both the hydrostatic overbalance and thedynamic pressures are adequately managed, otherwise losses or influx may result. Our

preliminary study addresses this limitation. At present, there is no proper understandingabout the flow behavior changes with down-hole conditions for an oil based mud and thereasons are: 1) The simple two-parameter constitutive models, such as the Bingham Plastic or

Power Law models are not adequate especially in HP/HT situations; and 2) The rheology ofthe drilling fluid is controlled by many factors, e.g. temperature, pressure, shear history,composition and the electrochemical character of the components and of the continuous fluid

phase. And, these effects are: 1) physical effects; 2) electrochemical effects: and 3) chemicaleffects. The temperature at the bottom of the hole increases as the depth of the well increases.Then, the drilling fluid temperature approaches the geothermal gradient when it is not being

circulated during a trip or on logging runs. However the temperature of the fluid is always ina transient state strongly sensitive to the flow rate. A drilling fluid’s viscosity is related to thedown-hole variations in pressure and temperature and is a very important part of drillingengineering. Finally, we report some of our basic results that help us in making advances intemperature modeling leading to a better understanding and development of some accurateinterpretation techniques.

V.Arunkumar

The present investigation is aiming to get better squeeze film dampers which are normallyused in high speed jet engines to minimize small amplitude large force vibrations. Theinvestigation was started with squeeze film dampers employing conventional lubricating oils.

Magnetorheological fluids are then used to enhance the viscosity characteristics of the fluidunder the influence of magnetic fields in order to improve the damper performances. It isobserved that the dynamic characteristics of the damper with magnetorheological fluids areenhanced. Further to improve the damper performance, few modifications in the damperassembly are carried out in this research work. A good amount of reduction in the amplitudeof vibrations is observed in these modified squeeze film dampers coupled with

magnetorheological fluids. This research work discusses dual and triple clearance squeeze film dampers and bump foil squeeze film damper, also subjected to variation in temperature. Dynamic characteristics are found to be decreasing as the viscosity of the fluid decreases withrise in temperature of the fluid.

I S Stephan Thangaiah, P Sevvel

A wind turbine performs the function of converting the energy (kinetic) derived from the wind

into another form of energy (mechanical) which is employed for the purpose of driving the generator which in turn generates electricity from this mechanical energy into. The mostcommon types of windmills employed in practice include horizontal and vertical axis windmills. These windmills are fabricated in different structures for producing electricity. Themain objective of this paper is to fabricate an innovative eco friendly windmill to overcomethe various difficulties existing in conventional windmills. In conventional windmills, the

propeller rotation depends on the velocity of wind flow in the environment. But in this paper,we have fabricated an innovative eco friendly windmill in which, the propeller rotation isincreased four times for the wind velocity in the surroundings.

Jayaganth, A. Deepak Mani, K. Jayakumar

Stainless Steel 304 (SS304) is a non magnetic material and has excellent corrosion resistanceand forming characteristics which is mainly used in chemical, petrochemical, aerospaceindustries, etc. Few examples are kitchen wares, cryogenic vessels, surgical equipments andheat exchangers. However, most of these components require different machining processesto produce the desired product or assembly. But, during machining of SS 304, industries are

facing major difficulties such as high tool wear and poor surface finish due to low thermalconductivity and high built up edge (BUE) tendency. Many researchers started workingtowards machinability of SS304 in different machining processes. Among these, few workshave been started on drilling of this material. Drilling process is mainly used for assembly of

structural parts and also used as primary process for boring, reaming, etc. By considering theabove applications and challenges in machining of this material, the present study analyzesthe effect of cutting speed, feed and machining environment on surface roughness andmachining time during drilling process. Drilling experiments have been conducted in a jigboring machine using 10 mm diameter HSS twist drill bit by varying cutting speed (16, 22 and28 m/min), feed (0.08, 0.12 and 0.16 mm/rev) and machining environment (dry, normal

soluble oil flood coolant and kerosene) as per Taguchi’s L 9 orthogonal array. The resultsindicated that, average surface roughness (Ra) increased from 2.088 µm to 6.647 µm whenincrease in cutting speed and feed. Roughness value decreased for kerosene environmentcompare to dry and coolant environment. Also, machining time decreased from 15.01 secondto 5.58 second when increase in cutting speed and feed along with kerosene environment

compared to dry and flood coolant condition.

K. Babu

In striving to remain competitive in the global market, the concept of optimization ofmanufacturing processes has been extensively employed to meet the diverse productionrequirements. Optimization analysis of machining processes is usually based on eitherminimizing or maximizing certain objective functions. Recently, various non-traditionaloptimization techniques have evolved to optimize the process parameters of machining

processes. The objective of this work is to study the effectiveness of the most commonly usednon-traditional optimization methods as applied to a particular machining optimization

problem. In this work, surface grinding processes are optimized using i) Particle SwarmOptimization (PSO) ii) Adaptive Genetic Algorithm (AGA) iii) Simulated Annealing (SA) andiv) Memetic algorithm (MA). Memetic algorithm used here has two variations as MA-1 and

MA-2, each having the combination of PSO and SA and AGA and SA respectively. Themathematical model of surface grinding operations was adopted from a literature. Acomputer program was written in Visual C++ for the optimization computations. Thecomputation results of various optimization methods are compared and it is observed that theresults of PSO method have outperformed the results of other methods in terms of thecombined objective function (COF).

V.E.Annamalai, M.J.Hepsi Beaula

Any grinding wheel has pores upto 20%. In a grinding situation, when the wheel contacts theworkpiece material and grinds, it is literally difficult for the coolant to reach the grinding

zone. An attempt is made to create capillary action in the grinding wheel by aligning the pore structure of the wheel and interconnecting the pores-to form a capillary like pore channel.This is done at the grinding wheel fabrication stage at the manufacturer's end.

AB16714 Effect of SiC p reinforcement on machinability of A356 alloy metal matrixcompositesK. Jayakumar

Machining of Aluminum Metal Matrix Composites (AMMCs) is a challenge for manufacturingindustries due to their heterogeneous constituents which vary from soft matrix to hardreinforcements and their interfaces. To overcome the difficulties in machining of MMCs,researchers are continuously working to find the optimum process or machining parameters.

In this work, End milling studies were carried out in A356 alloy powder- SiC particles (1 µm)in 0, 5, 10, 15 volume % reinforced AMMCs synthesised by vacuum hot pressing (VHP) route.The influence of machining parameters such as cutting speed, feed and depth of cut on the

prepared composites in terms of surface roughness (Ra) and material removal rate (MRR) aremeasured from experimental study. Experiments were conducted as per Taguchi L 16 orthogonal array with 4 factors and 4 levels. From the experimental result, it was identifiedthat surface roughness varied from 0.214 µm to 4.115 µm and MRR varied from minimum of1.11 cm 3 /min to maximum of 9.65 cm 3 /min. It is also observed that, MRR increased withincrease in machining parameters and reinforcement quantity. Similarly, surface roughness

decreased for increase of cutting speed, SiC particle (SiC p ) reinforcement and increased forincrease in feed and depth of cut. The optimum condition were observed in higher speed,

temperature difference of 20.12% is obtained when conventional and cryogenic models werecompared at a feed rate of 0.07 mm/rev and cutting speed of 150 m/min. cutting force andthrust force were higher for cryogenic model compared with that of the conventional model.Stress and Strain were distributed as expected to occur in the experiment.

AB16593 A Breif Review On Numerical Studies On Film Cooling Effectivenes

Prakhar Jindal, Shubham Agarwal, R.P. Sharma

Film cooling is employed for effective cooling in nozzles and combustion chambers using a

spray of coolant fluid in the mainstream flow to cool the body. Experimental analysis was performed elaborately in the past years to get an exact analysis of film cooling effectivenesswith different parameters. This approach was however discouraged due to its high cost andtime consumption. Recently, researchers switched to the use of numerical platforms forinvestigation of complex film cooling systems. The paper discusses in detail the numericalanalysis of the film cooling systems done so far and the numerical models employed for such acomplex analysis along with the advantages and trade-offs of such a numerical approach.This study was carried out to extend database knowledge about the numerical film cooling forits various applications. Therefore, an appropriate cooling technique should be designed to

protect these parts. Film cooling is one of the most effective external cooling methods.Various numerical film cooling techniques presented in the literature have been investigated.

Moreover, challenges and future directions of numerical film cooling techniques have beenreviewed and presented in this paper. The aim of this review is to summarize recentdevelopment in research on film cooling techniques and attempt to identify some challengingissues that need to be solved for future research.

AB16625 An Experimental Study on Natural Convection Biomass Dryer with differentSensible heat storage materials

D.V.N.Lakshmi, S. S. Mohapatra, H. C.Das

The state Odisha of India is mainly an agro based state and maximum percentage of population of the state depends on cultivation. Rice is the main cultivation crop here. Postharvesting losses are more due to lack of proper knowledge of farmers. Farmers used to dry

paddy with open solar drying technique before storing. The main problem in this technique isthat there is no control in the amount of heat transferred to the items which gradually leads tocracking of grains. One of the best possible solution is to dry the grain by using biomass graindryer. In the present research work, an efficient and effective biomass burner with fins isdesigned and fabricated at SOA University in city of Bhubaneswar, Odisha to dry the paddyby using sensible heat storage materials. Two different sensible heat storage materials pebbleand concrete have been used to dry 10 kg of paddy in a batch wise drying process. Theaverage moisture content of fresh paddy of 29.2% was dried to 14.8% in 240 minutes by using




63

pebbles and by using concrete time taken to reach desire moisture content is in 210 min. Thetime taken by this process is less than the conventional drying without storage materials. Thetemperature near the paddy tray was maintained in a range of 50 – 58 °C which is acomfortable temperature for paddy drying. The efficiency of the dryer with pebbles andconcrete also calculated and better efficiency is observed with concrete as sensible heat

storage material.

Transfer function is extensively used in the analysis and design of linear, time-invariant system by characterizing the input-output relationships of the system. The interface betweenmathematics and biology has been initiated and fostered in this paper. This paper presents anovel and simple mathematical model of the temperature, flow and the pressure. In manyareas of scientific research and production practice, the temperature is an important physicalquantity need to be measured and control. A temperature control system which includes both

feedback signals based on the blood temperature and the heat flux is postulated and values ofthe transfer function for PID parameters setting for temperature module have been used in

simulation similar to the real system controller. With the help of continuity and Navier -Stokesequations, a simple differential equation was derived known as the master equation and basedon the logical assumptions the basic mathematical model of the normal blood flow wasdeveloped and is reduced to a system of ordinary differential linear equations of the firstorder. Then this model was extended for normal blood pressure with the Poisuelli's equation.With derived transfer functions, the simulation procedure has been carried out in MATLABSimulink using different controllers like PI, PD and PID controllers and these results arecompared and analysed. For the stabilized closed loop system, PID controllers are designedbased on the identified First order plus time-delay (FOPTD) model which is tuned by Ziegler-

Working memory (WM) is an imperative process for reasoning, comprehension, learning andmemory updating and it is accountable for the transitory holding and processing of new and

previously stored information. The aim of this study is to examine the effect of guidedmeditation on working memory. The purpose of this study is to acquire the working memorytask performance scores prior to and after performing a brief period of guided meditationwhile recording the electroencephalograph (EEG). Random, healthy adult participants withno exposure to any kind of yoga or meditation techniques were chosen for this study. TheWMC of the participants was evaluated with the help of OSPAN task. The same group of

participants was used to perform the task before and after a brief period of guided meditation. At the end of the task, five scores were documented in the database with which the task performance of the participants can be assessed. The task performance scores like Ospan score and total number correct score were significantly high (p = 0.005) while performing thetask after a brief period of guided meditation in contrast to the task performance scoresbefore subjecting to a brief period of guided meditation. Also, the math errors were reducedwhile performing the task after a brief period of guided meditation. EEG frequency bandswere extracted and the power of each frequency band was calculated. The ongoing rhythmic

EEG activity was useful for distinguishing an internally generated mode of intended encoding

described by alpha desynchronization and theta synchronization. The task performance scores were correlated with the power of alpha and theta frequency bands of EEG. Based on




72

the results, the study concludes that a brief period of guided meditation imposes a significanteffect on the task performance indicative of the improvement in the working memory capacity.

AB16563 Determination of Material Removal Rate and Radial Overcut in ElectroDischarge Machining of AISI 304 using dimensional analysis

Munmun Bhaumik, Kalipada Maity, Kasinath Das Mohapatra

Electro discharge machining (EDM) is a most commonly used machining process among allthe non-conventional machining process which removes materials via electrical and thermalenergy. The primary goal of EDM is to get more material removal rate (MRR) with lowerradial overcut (ROC). Normally, the responses are predicted using empirical models which

are limited to only machining parameters and they do not consider the effects of workmaterial properties on the process performance. Therefore in this study, a model has been




73

developed including machining parameter as well as thermo-physical property of workmaterial. In this investigation, a semi-empirical model has been established for the materialremoval rate (MRR) and radial overcut (ROC) by adopting the dimensional analysistechnique. Dimensional analysis is a technique of dimensions and a mathematical techniquethat deals with the physical quantities concerned with the experiments to formulate a model

for the response in terms of response control parameters as well as some physical propertiesof the materials. Buckingham’s л theorem is a main theorem in dimensional analysis and it isa signification of Rayleigh’s method of dimensional analysis. The theory is applied to gathereach and every variable presenting the problem in a number of the dimensionless products.

For this study, the thermo-physical properties viz. density, thermal conductivity andcoefficient of thermal expansion and machining parameters like peak current, pulse on time,

gap voltage and duty cycle are considered as input factor. AISI 304 stainless steel used aswork material and Tungsten carbide is used as tool material for this investigation.

AB16590 A Case Study on Insulating Main Steam Line (MSL) with Silica Aerogel

J.Manohar,S.Ramprakash, G.Selvakumar Dhiliban

In this paper, a case study on replacing the existing insulating material (Mineral wool) by theSilica Aerogel in the main steam line (MSL) of the thermal power plant is presented.A samplelength of 3 m in MSL was insulated with various thicknesses of silica aerogel, mineral wooland the combinations of mineral wool and silica aerogel. The heat loss in the sample lengthwith different insulating material was calculated by carrying out field experiments. Theresults show that the silica aerogel is providing better insulation than the mineral wool.

Nonetheless, the use of silica aerogel is expensive. To bring down the cost, hybrid insulationwith the optimal thickness of silica aerogel + mineral wool + silica aerogel was suggested.This hybrid combination considerably reduced the heat loss and improved the thermal

efficiency. The payback period for this implementation was reported.

AB16598 Estimation of aerosol emission in die sinking EDM process through numericalmodelling

M. Nalla Mohamed, J.Sylvya Rebecca

Emission of metallic particulate (aerosol) is an important hazard associated with the EDM process. These emissions can cause adverse health effects to the operators and has a directimpact on the environment. Therefore, concurrent investigations of the aerosol emission andmachining aspects of the EDM process are essential for achieving hygienic and efficient

machining. The aerosol emission from the process is directly related to the temperature at the process location. Hence, this paper first addresses a numerical model that quantifies thetemperature distribution on the surface of a work piece and tool using ANSYS® 14.5. Themodel first calculates the temperature distribution in the workpiece material and then

Material Removal Rate above the boiling temperature of workpiece and tool were estimated from the temperature profiles. Then, a model that quantifies the aerosol generated from EDM process is developed using energy balance and heat transfer equations. Validation of modelhas been done by comparing the results against the published experimental results obtainedunder the same process parameters. A good agreement was found between the experimentaland numerical results. The model used in this paper can predict the level of emissions atdifferent process locations in order to suggest suitable process conditions for green

manufacturing.

AB16662 Experimental Prediction and numerical modeling of Ductile Damage andFailure Modeling of Aluminium sheet metal specimen

M.Nalla Mohamed, Praveen Kumar.A

Aluminium sheet metal is nowadays used to fabricate lighter, crashworthy, fuel efficient andenvironment friendly vehicles. Ductile damage of sheet metals affects significantly thecrashworthiness, as it naturally exhibits anisotropic behavior due to the grain orientation.

Johnson-Cook (J-C) damage model is widely used in numerical simulation for assessing the failure modeling of crash component in particular at high strain rate. The Johnson-Cookmaterial model available in literature is meant for isotropic material behavior which cannotbe used directly for anisotropic behavior of materials. To characterize the plastic anisotropyof the rolled sheet, the modified Johnson-Cook material model should be developed. In thisresearch the combination of experimental work and numerical analysis with clear and simplercalibration strategy for damage model is demonstrated. It aims to reduce laboratory testsusing advanced numerical analysis to predict failure in order to save overall cost and

development time.

Praveen Kumar.A, M.Nalla Mohamed, Nikhil.N, Dhilepan.K

Increasing demand for special materials leads to new inventions. One of the most promisinginventions is the concept of composites. Natural fibers have the potential as a reinforcingmaterial as an alternative to the use of glass, carbon and other synthetic fibers in automotiveindustries. Among various natural fibers, Kenaf is a widely used fiber due to its easyavailability, low density, low production cost and satisfactory mechanical properties. Toenhance the mechanical properties of natural fibre composites, strengthening of the matrixand fibre is very much essential. A prospective reinforcement in this regard is fly ash, which isabundantly available as a waste product from thermal power plants. In this paper, a newnovel natural composite with epoxy as a resin and reinforcing both bio waste (Kenaf) andindustrial waste (Fly ash) has been developed. All the laminates were prepared with a total of4 plies. Laminates without fly ash filler were also fabricated for comparison purpose. A handlay-up method was used for the fabrication of composites and was tested as per ASTM

standards for evaluation of tensile properties. The effect of fly ash weight percentage (5, 10,15% wt.) on tensile properties was studied experimentally. Due to the incorporation of fly ash

fillers into the kenaf fiber composites, there is considerable improvement in the mechanical

properties. Overall results supported the effective utilization of natural composites forautomotive applications.

The application of Metal Matrix Composite (MMC) has been increasing due to its superior strength and wear characteristics but the major challenge is its poor machinability due to the presence of reinforcement in the matrix which is a hindrance during machining. The materialbehaviour during machining varies with respect to input variables. In this paper the effect ofcutting speed during the orthogonal turning of A359/SiCp MMC with TiAlN tool insert isanalysed by developing a 2D Finite Element (FE) model in Abaqus FEA code. The FE modelis based on plane strain formulation and the element type used is coupled temperaturedisplacement. The matrix material is modeled using Johnson – Cook (J-C) thermal-elastic –

plastic constitutive equation and chip separation is simulated using Johnson –Cook’s model for progressive damage and fracture with parting line. Particle material is considered to be perfectly elastic until brittle fracture. The tool is considered to be rigid. The FE modelanalyses the tool interaction with the MMC and its subsequent effects on cutting forces fordifferent cutting speeds and feed rates. The chip formation and stress distribution are also

studied. The FE results are validated with the experimental results at cutting speeds ranging from 72 – 188 m/min and feed rates ranging from 0.111 – 0.446 mm/rev at constant depth ofcut of 0.5mm.

Sundaresan.J, S.Senthil kumaran

Aluminium based metal matrix composites (MMCs) offer potential for advanced structuralapplications when high specific strength and modulus, as well as good elevated temperatureresistance, are important. In the present work, Aluminium matrix composites (AMCs)reinforced by ZrB 2 and TiB 2 particles were fabricated from Al 4032- x wt% ZrB2 andTiB2(x=0,2,4,68) by in situ reaction from mixtures of K 2 ZrF 6 ,K 2TiF 6 and KBF 4 with molten Alalloy. The composite wear test were conducted using on pin – on disc machine Materials

possessing high wear resistance (under dry sliding conditions) are associated with a stabletribolayer on the wearing surface and the formation of fine equiaxed wear debris. Foradhesive wear, the influence of applied load, sliding speed, wearing surface hardness,reinforcement fracture toughness and morphology are critical parameters in relation to thewear regime encountered by the material. The composite flakes was developed usingTaguchi’s method by considering the parameters of composite %,speed(rpm) , load(N).Theresults indicate that the volumetric wear rate is decreased with the increase in the weight

percentage of ZrB 2+TiB 2 , while it is increased with the increase of the applied load. The SEManalysis of the wear scar indicates the fragmentation of ZrB 2+TiB 2 particles into smaller onesorienting themselves along the sliding direction. The SEM analysis of the wear scar indicatesthe fragmentation of ZrB 2+TiB 2 particles into smaller ones orienting themselves along the

M.Selvaraj, G. Selvakumar, M.S. Alphin

The heat generation during friction stir welding process influences the material flow,

microstructure, and mechanical properties of the friction stir welded plates. This paper proposes a model for predicting heat generation and heat flux during the friction stir weldingof AA 6061 aluminium alloy. The heat generation as a function of temperature, heat flux atthe shoulder as a function of temperature, radius of shoulder and rotational speed and heat

flux at the pin as function of temperature, radius of shoulder and rotational speed have beendiscussed. It shows that heat generation is inversely proportional to temperature, the heat fluxat the shoulder and pin are directly proportional to radius of shoulder and rotational speedand inversely proportional to temperature.

Poovazhagan.L , Amith.S.C, Magesh.S, Naveen.D

Nano particulates reinforced aluminum metal nanocomposites are prospective materials foraerospace, automobile, sports, and marine industries because of their superior strength toweight ratio and high temperature bearing properties. In this work, novel ultrasonicationassisted casting method was used to fabricate different weight percentages (0, 0.5, 1.0 and1.5) of SiC nanoparticulates reinforced aluminum alloy 6061 nanocomposites. The followingresults were observed from hardness test, impact test and grain size measurements. Increasein weight percentage of nano-SiC in aluminum matrix leads to significant improvement inmicrohardness, which was confirmed by Vickers-microhardness tests. Compared to themonolithic aluminum, the maximum improvement in microhardness of around 47 % wasobserved in 1.5 weight percentage SiC reinforced composites. Optical microscopic images

showed refined aluminum grains in nanocomposites compared to pure alloy. Impactresistance of aluminum matrix was almost retained with an addition of SiC nanoparticles.

Impact fracture surfaces of both pure alloy and nano composite exhibit the combination ofductile and brittle fracture.

Vaishnavi.D, E.Sundari, Sangeetha.T.V, S.Shrinidhi and P. Saravanan

In today’s fast paced world, transportation plays a very important role. Of all the differenttypes of transportation available, cars are one of the most common and most preferred meansof transportation for the majority of people. The classical Cruise control System maintains the

pre-set speed and will also adapt itself to the change in acceleration of the preceding vehicle. But it is not sophisticated enough and reduces its speed to zero in case of critical conditions. In the proposed system, in addition to obstacle detection, a new feature is added whichenables the vehicle to switchover to an empty lane when the preceding vehicle is too near orwhenever there is a possibility of crash. This paper discusses about the implementation of the

same. The main input to the system is the data collected by the ultrasonic sensors fixed to the four sides of the vehicle. The main processing unit analyses the data collected and sends out acontrol signal to the motor driver in accordance with the algorithm. H-Bridge in this systemcontrols the speed and the direction of the vehicle by giving the appropriate control signal tothe motor connected to the wheels. This paper deals with the design of the prototype model of

the proposed system. The main control part of our system is realised by the Arduinomicrocontroller.

R.Ranjani , M.Nandhini,C.Arun Prakash

This paper deals with an autonomous external glass cleaning robot that can perform theoperation by ensuring proper adhesion to the glass as well as movement along the entirewindow without colliding with the window pane or any other obstacle. The concept used inthis work to actuate the robot is pneumatics wherein a pneumatic cylinder is coupled with a

linear channel made up of stainless steel. It has a guide and a block which are connectedthrough a chain and sprocket. The block can move along the guide. The piston of the cylinderis coupled with the block while the cylinder barrel is coupled with the guide. Adhesion of therobot to the glass is ensured using the vacuum technology. Four suction cups are used tomake the robot adhered to the glass. Two channels are placed at right angle with each other,one for horizontal motion and one for vertical motion. Stepwise movement of the robot isachieved by individual control of suction cups. This is done using the software Arduino and

Arduino UNO R3 microcontroller. Ultrasonic sensors are used to measure the dimension ofthe window pane as well as detect the obstacle/edge of the window. The cylinders and vacuum

generators are actuated using solenoid DCV’s. As the robot moves, a rot ating disk located atthe bottom of the robot has a cleaning brush/sponge attached to it which cleans the glass asthe robot and hence the entire glass surface is covered and cleaning operation is performedautonomously. The advantage of this robot is its simple design and its feasibility. The fact thatwe are able to successfully move the robot on a vertical glass frame without damaging itallows us to use it for several other applications too such as inspection.

AB16857 Advanced Handling model of a two axle vehicle with rigid suspension

S. Vishnu, Suryanarayana Prasad A.N, K. Kamalakkannan

Ever since the evolution of automobile, need for improving the safety is increasing day by day.

Handling behavior plays a major role in defining the safety factor of a vehicle. Duringcornering, vehicle experience relative yaw motion between sprung mass and unsprung due to stiffness on suspension bushes, which has a direct impact on handling.Literature surveyreveals that a significant research is done in vehicle dynamics simulations, but relative yawangle between sprung and unsprung mass due to compliance on suspensions bushes areconsidered very low and are often neglected. Available computational software has alimitation in as much as they require more number of inputs and optimization of vehicle

parameters requires more time and effort. Simulating the relative yaw angle helps to design suspension bushes and linkages.This work attempts to address the above issues through development of an advanced roll yawcoupling model. The vehicle is considered as a three rigid body system (sprung mass, frontunsprung mass and rear unsprung mass) with 7 degrees of freedom. Inertial couplings,conical stiffness of suspension bushes and roll steer effect, are taken into account to establisha complete relation between roll and yaw dynamics. The effect of aligning torque due to




83

caster angle is also included; however the developed model is not implemented for optimizingvehicle parameters. Equations of motion are derived for a two axle vehicle having leaf spring

suspension, based on force and moment balance in different vehicle planes. The equations arerepresented in state space form and a numerical integration using Runge Kutta method isdone in Matlab® to solve the system of equations with inputs for transient cornering.

Md.Rabbani, R.Natarajan

Everything that happens in the world is an expression of energy in one of its forms. “Energycan neither be created nor be destroyed. It can only be converted from one form intoanother”. So wind energy is converted from one form to another. Wind energy is readilyconverted into mechanical energy through the turbine blades. This mechanical energy can beused for saw milling applications. In this paper we concentrate on Design of Shaft, Bevel gearand Torque Transmission system and we analyze the aerofoil cross section blade using

ANSYS 10.0.

AB16788 Acquisition and Analysis of electricity using Piezoelectric materials inautomobile wheels

Alphin M S, Arun K V J, Ebenezer D

Piezoelectric materials which are going to change the electricity production for lower usagein future demands. Piezo materials which are available in nature and can also be madeartificially helps in the electrical generation due to the application of stress on the crystals.This unique behaviour application of stress on the crystal motivated us to introduce in thewheels of the automobiles which helps in the elimination of alternators to produce electricity

which is done by the deformation caused by the tires which is in contact with theroad surface. The produced electricity can also be used for the minimal requirements such asusage of visors, glass operating motors, interior lightnings, etc. Crystals such as quartz,

sugar, tourmaline, barium, and zirconium titanite exhibit this property, of those, we chosequartz of size diameter 2.5 mm which can be easily produced is soldered in series formaximum generation. Then the setup was placed on the kinetic Honda rim of the wheel and

the tube an Tyre were placed above that with the little rotation of the wheel against the surface caused the deformation in Tyre which in turn deflected the crystal surface which produced electricity of 0.66 V and it was measured by the data logger further it was stored inthe battery. At few points volts produced were recorded as 0.66 volts. It was observed thatmaximum of 1.33 volts was produced when 2-3 piezo crystals were stressed due to tirecompression. The tire compression produced here is a result of applied weight in the range 5-12 kgs. The produced charge can be potentially stored in a capacitor for future withdrawal byautomobile equipment. Thus piezo electric energy harvesting can be effectively used as a

substitute for limited capacity batteries to elongate their useful life. Hence the application ofcrystal in the tyre were easy to fabricate and the less cost crystals produced electricity whichwill be a greater demand in future.

Sandwich structures based on Fibre Reinforced Polymer (FRP) facesheet skins bonded withlow density aluminium foam core are increasing in use in aerospace and marine industries.These structures are very sensitive to high velocity impact during the service. Therefore, it isnecessary to study the energy absorption of the structures to ensure the reliability and safetyin use. Experimental investigation of these transient events is expensive and time-consuming,and nowadays the use of numerical approaches is on the increase. Hence, the purpose of this

paper is to develop a numerical model of sandwich panels with aluminium foam as a core andGlass, Carbon and Kevlar Fibre Reinforced polymer composite as faceplate, subjected tohigh velocity impact using ABAQUS/Explicit. The influence of individual elements of the

sandwich panel on the energy absorption of the structures subjected to high velocity impactloading was analysed. Selection of suitable constitutive models and erosion criterion for thedamage were discussed. The numerical models were validated with experimental data

AB16855 Investigation to Evaluate Crash worthiness of a Truck cabin using FiniteElement Crash Simulation

Neeraj Kumar Mishra, Sharad K. Pradhan

A crash test is a form of destructive testing in order to ensure safe design in case of an impactor collision. These impact tests are carried out to understand a components structuralbehaviour and its response under different collision conditions. But it is not alwayseconomical to destroy a specimen to ensure its safety, especially in case of small scale

production. Moreover actual crash testing in different conditions requires high resources andtime. Crash simulation is very popular now a days because it is a virtual representation of adestructive crash test of a vehicle using a computer simulation in order to examine the level of

safety of the vehicle and its occupants in different conditions like collision velocity, collisiondirection, colliding object, material and number of component of colliding object etc andhence saves the time and cost. Data obtained from a crash simulation indicate the capabilityof the vehicle body to protect the vehicle occupants during a collision against injury. In this

study a FE crash analysis of commercial truck cabin in two different cases (Bare cabin and Loaded cabin) using Finite Element Approach (FEA) is focused. Crash analysis of truck cabis performed using FEA in order to predict the design parameters for minimization harm tothe occupants of the vehicle. A bare truck cabin and a rigid wall were used to simulate crashconditions with different crashing velocity and impact angles. CATIA V5R20 CAD software isused for the modeling of the selected cabin components followed by FE meshing through

Hypermesh and then analysis is done using LS-DYNA by setting the boundary conditions,material properties etc. appropriately.

S.Balaji, Sarat Unnithan, N.Ganesh, A.Kumarasamy

Next generation IC engines are designed to achieve high efficiency and high specific power. As a single most design driving factor, combustion pressure is increased more than before.This has major impact on the design aspects of cylinder head. Its features become moredelicate to accommodate various elements. Thermal aspects composing of heat generation (bycombustion); heat transfer (combustion, cooling water, intake and exhaust gas) makes thedesign more challenging. Methods to enhance the heat transfer and controlling bodytemperature are discussed by various authors. In this paper a high specific power enginecylinder head is analysed using coupled field analysis. To enhance heat transfer, inner flamedeck surface is configured as a curved surface instead of flat present in the conventionalcylinder heads. Effect of reduction in the cross sectional area due to curvature is analysedagainst flat surface. It is found that this new approach reduces the flame deck temperature




considerably without compromising the structural strength factors. CFD, steady state thermaland structural analysis has been carried out for four different cases to conclude the extend ofeffectiveness due to curvature.
