RESUMEH.NIRMAL KUMAR - B.E, Phone: 9028692482,Email: lamrin72@gmail.com

OBJECTIVE: To work in an environment that will help in my technical growth and at the same time serving the organization to fulfill my responsibilities to the best extent.

SPECIFIC EXPERTISE:Professional Experience of 3 years as an FEA Engineer which involves extensive experience in FE modeling and analysis of Automotive and Aerospace components.

PROFESSIONAL EXPERIENCE:Organization: Quality Engineering & Software Technologies Pvt Ltd, BangaloreDuration: Nov 2015 – Till date

Organization: Analyzer CAE Solutions Pvt. Ltd, PuneDesignation: FEA EngineerDuration: June 2013 – Oct 2015

Currently working as a FEA Engineer in “QuEST Global“, Bangalore. I am responsible to perform analysis on gas turbine engine Installation and complex fabrication components attached to the engine casing. In addition to that I’m also responsible for analyzing the components based on the application standard loads.

PROJECTS EXECUTED AT QuEST:Title: Trent 7000 Mineral Insulated (MI) Disconnect Panel AssemblyClient: Rolls-Royce

Normal Mode Analysis:The MI Disconnect panel supports the terminal blocks and the Oil scavenge pipe which is attached to

the LP-IP turbine casing. Dynamic analysis simulating free vibration to predict stiffness and dynamic behavior of the bracket is performed. The modes and natural frequencies were further correlated with experimental test data. The critical modes of components which are not meeting the modal analysis criteria are further undergone forced vibration, Dynamic stress, and fatigue calculations.

Frequency Response Analysis:The Forced Vibration Analysis (FVA) or frequency response analysis is carried out for the critical

modes which are lying within the engine operating range. Stresses are evaluated where the peak response is obtained. Further, the vibration stresses are combined with the mean stress for HCF assessment. The recast layer due to laser cutting on these sheet metal brackets are instructed to be kept/removed as per the requirements.

Title: Trent 7000 Power Door Operating System (PDOS) brackets.Client: Rolls-Royce

The PDOS brackets allows the fan cowl doors to be opened using powered actuators rather than being opened manually, which are provided on either side of the engine. Bumper brackets are provided to support the actuator when it is disconnected from the engine. Linear static analysis was performed at both

closed and open conditions of the fan cowl door under operating conditions. Further, bolt assessment is carried out to check the structural integrity of the joint.Title: Trent 7000 Engine Lease Plate AssemblyClient: Rolls-Royce

Dynamic analysis for the Engine lease Plate assembly is carried out and the fundamental frequency of the bracket assembly is found outside the engine operating range.

Inertia Analysis: The structural integrity of the sheet metal bracket is assessed by performing Inertia analysis in all three directions individually. The HCF assessment was performed by considering the inertia stresses as the dynamic stresses and compared with the fatigue limit.

PROJECTS DONE AT CRTI (Cummins Research & Technology India): Thermal Yielding (Stress to Strength ratio) Analysis for Exhaust manifolds:

The main objective of the SSR analysis is to examine the manifold for yielding under a static high temperature condition. The process is carried out for torque peak engine operating conditions considering the worst case depending on the engine calibration and operating environment. CCI (Cycles to Crack Initiation) Analysis:

This is a transient thermal analysis meant to capture the high stresses that can occur during transient engine operation. Due to the different abilities of regions within the manifold to retain and loose heat, temporary high stress regions may occur that are not present during steady state engine operation. CCI analysis is performed only if the manifold does not yield under the worst case conditions (SSR). Static Analysis:

The static analysis has been carried out for bolted joints in an assembly under the action of loading under different scenarios as per the engine standard application. Loading environment includes assembly loading (bolt preloads, pressure etc), external loadings (inertia loads) and the combination of these. Majority of analysis carried out for engine block, fuel pump, water pump and fuel pump supports and gear housing. Bolt joint analysis has been performed by modeling it as beam using Ansys APDL and also as 3D model of bolt using Ansys WB for both dynamic and external static load cases.

Dynamic Bolted Joint Analysis:Bolted Joints in Cummins are classified based on the temperature they undergo, Cold Joint

(below 2320C) and Hot Joint (above 2320C). This analysis intends to design a new hot bolted Joint analysis for bolt selection, material, need of spacer and washer etc. Also, analyzing the existing hot bolted joint for comparative analysis perspective or for further design improvements.

UG – PROJECTS DONE: CFD ANALYSIS OF PULSE DETONATION ENGINE:

The main objective of pulse detonation research is to develop an efficient engine that is primarily used for high-speeds (potentially Mach 5), as well as high-altitudes. The basic concept behind the technology is to detonate, rather than deflagrate, the fuel. The detonation of fuel results in immense pressure, which in turn is used as thrust. The main aim of our project was to study the pulse-jet engine to overcome its major drawback of buzzing noise production, to eliminate this; we replaced the flapper valves by 2 discs. The next step is to design a pulse detonation engine using CATIA software and its analysis was done using ANSYS CFX. EXTRA-CURRICULAR ACTIVITIES:

Industrial visit to INDIAN AIR FORCE at Tambaram, and educated about the various integrated technologies about the Radar and space navigation.

Participated in Aero-modeling Workshop held in Jaya Engineering College.

Participated in Cad modeling & Quiz competition held at St.Peter’s University.

STRENGHTS: A good team player with capable of executing the given job within time. Good communication skills and a quick learner.
