PROFESSIONAL EXPERIENCE
General Motors Technical Center India Limited, Bangalore, India (Current Employer)
Role: Senior Engineer Engine CAE
Aug 2012 – Present (2 Years 6 Months)
Key Projects:
1. Pseudo sound power analysis of Engine block to identify reason behind increase in the
block noise (GM Europe)
- Sound power analysis was performed on engine block considering five different load and
engine mass criteria.
- A study is done to understand the reason behind increase in the sound level in the engine
block compare to old design.
- Suggestions were given to the design engineer to reduce the noise level.
2. Finite element modeling of Teflon connector between turbo oil feed pipes to calculate
dynamic stress of turbo oil feed pipes due to engine combustion loads.
- Turbo oil feed pipes with Teflon connector showed structural failure in the experimental
test. The established modeling technique was unable to replicate failure in the analysis.
- Study is carried out to develop modeling method to model Teflon connector and it was
observed that Orthotropic material modelling could replicate the failure of the turbo oil feed
pipes as per experimental test.
- Material properties of orthotropic material were calculated using experimental information
available and verified the same with the other engine available.
- The damping properties of the Teflon material were tuned to get analysis results close to
experimental data.
3. Topology Optimization of AC Compressor bracket for frequency and Dynamic stress
Constraint.
- This analysis was carried out as a part of an optimization study on the AC Compressor
bracket using OptiStruct.
- The constraint for this activity was frequency as well as dynamic stress and the target was
to reduce the mass of the component.
Key accomplishments:
- The guideline design of the bracket obtained which was satisfying both frequencies as well
as maximum dynamic stress criteria by achieving 27% mass reduction.
4. Design suggestions for Converter brackets of exhaust system of Diesel engine using
dynamic stress analysis.
- This analysis is done to calculate dynamic stress on exhaust line and converter brackets
due to engine loads.
- Some of the converter brackets were not passing endurance limit value.
- Design modifications were suggested on the basis of dynamic stress analysis results.
Key accomplishments:
- New suggested bracket design was successfully passing the Endurance limit value.
5. Powertrain modal analysis.
- This analysis is done to calculate bending modes of Powertrain.
- This analysis gives information, whether the Powertrain bending frequency is higher or
lower than the operating engine frequency.
