Being an
affordable FEA solution, Cosmos FEA has been well-received by the
automotive industry for system-level as well as component level
analyses involving critical design functions on one side and aggressive
cost/ weight targets on the other. To be globally competitive,
the automotive suppliers have used Cosmos FEA to improve reliability,
eliminate field-failures, optimize designs and enhance efficiency very
easily. Specific capabilities include the following:
- Strength, Durability, Factor of Safety &
Stiffness calculations for Body-in-White, Trim-body, Chassis aggregates
- Frequency response for multi-source excitations
including Random Response
- Response to Fixed and Variable Frequency
excitations with specified accelerations – Engine and Body mounted
sub-systems
- Fatigue and Life Prediction Calculations
- Thermal management of braking and exhaust
systems
- Evaluation of alternate materials to satisfy
functional requirements
- Fluid Flow in Sub-systems such as Fans,
Radiator, Centrifugal pumps and Turbo-chargers
- Thermal management of Engine Electronics
- Analysis-to-test correlations of strains,
frequencies, mode-shapes, temperature, displacements, velocities and
accelerations
- Full-vehicle simulation of vehicles, buses,
trucks, utility vehicles, loaders, trailers among others
