Summary

A competent CAE Analyst with 10 years FE modelling & Analysis experience of various products

Expertise in Crashworthiness - Full vehicle and Subsystem level

Possesses good manufacturing and assembly knowledge of both metallic and non-metallic parts

Excellent problem solving & analytical skills

Adaptive & quick learner

Crash related highlights:

Test correlation for full frontal impacts through building high fidelity FE model for passenger car airbag sensor calibration for Japanese OEM:

Complete FE modelling of passenger car and assembly of all the subsystems

Defining various kinds of joining techniques during the assembly

Appropriate usage of material models, contact interfaces and control cards in LS Dyna

Dummy positioning for driver and passenger

Running explicit FE analysis for Full frontal, Pole test, Offset deformable barrier, Oblique tests at different speeds using Dyna

Interpretation of energies and comparing simulation results with test in terms of systems' behaviour and sensor deceleration pulse for airbag sensor calibration

Results were 85% in agreement when compared to that of tests

Occupant safety systems design verification though finite element methods for European Tier 1:

FE modelling of airbag housing, cover and airbags including their folding followed by positioning

Defining inflator information, tear line and other dynamic properties of gas

Performing dynamic simulations for airbag system integrity and airbag deployment - Knee airbags, Passenger airbags and Driver airbags

Interpretation of the results and design suggestions

20g Cab retention analysis of commercial truck per SAE J2418 for NA truck manufacturer:

FE modelling of cab, suspension and partial chassis & making sure that mass and CG of the cab are properly captured

Defining rear suspension shocks, restraint strap, airbags and mounting brackets with proper stiffness and damping

Running explicit LS Dyna simulations for frontal impacts to verify the integrity of the cab on the chassis frame rails

Extracting bolts, shocks, strap forces to validate the design

Comparing the seat base deceleration pulse with SAE standard curve

Major Achievements:

Supported by providing design solutions throughout the program in the development of hood assembly for severe service commercial truck

Designed & validated CCV heating system to avoid freezing at low temperatures for 10-40kW Genset

Built a team for supporting Occupant safety related product CAE verification activities for European Tier 1

Started and led a team for Seating design verification per FMVSS & ECE regulations for European Tier 1

Led a CAE team for engine mounting bracket design verification for Epsilon, Delta & Saab programs for an OEM
