Improved Structural Analysis through MultidisciplinaryIntegration by AIRBUS

Application to


Optimisation, Thermal

analysis, …to come

• Scope : I mprove Structure Analysis

Multidisciplinary Integration (ISAMI)

We need Composite, Metallic, Static, Fatigue

& Damage Tolerance + Global F.E.M.

Provide a common structure analysis environment,

where the processes, methods, tools and data

will be fully integrated

ISAMI context


The cost of not doing anything

• No synergy across “Method and Tools” Department for Structural Analysis– Continuous increase of cost for maintaining current and “new” legacy tools

– No single area to develop brand new method

• In-service Costs Increase (e.g. stress repair)– Tools diversity and lack of common supported process for analysis directly generates over cost for

in-service activity..

• Cost increases by using different Processes/Method and Tools,

Manufacturing– Duplication of the full “eco-system (training, support, deployment)

– No possibility to balance the workload between sites, “show stopper” mobility

– No synergy / No competition possible at RSP / SC Levels

– Heterogeneity of technology used to build a single A/C, causing and creating technical difficulties in A/C

section boundaries


Main objectives of ISAMI

• Rationalize process, methods and tools

– Processes and methods harmonization across the Airbus sites (F, G, UK and S)

– Rationalization of number of tools

– Without losing local experience and know-how

• Multidisciplinary

– One common environment for Structure Analysis Disciplines

– Increase efficiency in decision making process

– Provide advanced process capabilities, allowing multi criteria analysis at A/C-level (weight savings)

• Extended Enterprise

– To be deployed for A350: Airbus provides (most of the case) the capability to external partners

– More than 50 % of end users for A350 are not Airbus employees

– Replacement of “local-to-site” Stress Tools by ISAMI solution

Conclusion

• A new Transnational Multidisciplinary Tool that embeds

overall Airbus know how has been developed for A350 XWB

A/C program.

• Fully deployed and supported on all Airbus sites

• Fully deployed and supported in the context of Extended

Enterprise (SOCATA France, PATEC Germany, GKN UK and

US, SPIRIT US, ABEC China, AERONOVA Spain, TAI Turkish

…. )

• More than 600 users at end of 2009, 1500 potential when

deployed to all programs

After 5 years of strong collaboration

ConclusionBenefits: Cost reduction

• All Legacy tool developments have been frozen

• New methods requested by A/C programs are

developed once

• A unique transnational support team has been set up

• A unique transnational training organization has

been created

• A unique transnational team takes care of

Modules of S4WT Package


• Graphical model representation

• Manage models– list of different models for each component– Different designs– Different levels of details– Pre-existing or user define

• Components are automatically assembled

• Access to model parameters– Create and manage multiple load cases– Create and launch various analyses– Post-process results

S4WT Desktop: Global Models


• S4WT Modeler (SAMCEF Field)– Generate arbitrary, user-defined models for components

of the global wind turbine, e.g. a gearbox



• S4WT Solver (SAMCEF Mecano)– General purpose Finite-Element solver, comprising

kinematical joints– Solves non-linear equations of motion – Simulation process automatically initiated



• Variety of results:– Transient analysis

• Calculate time behaviour of global system

– Dynamic load amplification:• Estimate peak load amplitudes

– Spectrograph, FFT-Transformation• Show frequency content of time signals

– Fatigue analysis:• Estimate life time of components

– Modal analysis: • Calculate eigen frequencies

– Campbell analysis: • Detect potentially amplified eigen frequencies
