Replacement of a traditional combustion engine with an electric powertrain, brings electro-mechanical induced tonal and high frequency whine noise. In addition, tire and aerodynamic turbulent noise becomes more prominent in the absence of a standard Internal Combustion Engine. Also, the perceived sound quality imposes new set of challenges. This leads to new methods of NVH refinement, keeping the decades of research aside. Also achieving the target performance in a short development cycle time with minimal or zero prototypes is a major challenge faced by EV companies. To overcome these challenges, Altair with its partners have jointly developed a simulation driven process coupled with capabilities to virtually experience the noise and vibration characteristics, giving engineers a way to obtain real time performance feedback as the vehicle is being developed.

This workshop covers a wide range of topics, including benchmarking, target setting, full vehicle and motor gearbox simulation, load cases, troubleshooting, optimization & stochastic analysis, and playback of simulation results for subjective evaluations, with a number of new technologies representing the global best practice in sound and vibration design and development. Join us to explore ways to control the sound and vibration characteristics of the vehicle, achieve the right sound, and avoid common NVH pitfalls, while accelerating time to market utilizing and experiencing virtual NVH prototypes.

Who should attend?

This workshop has been designed for NVH refinement engineers (both Test & CAE) involved in the design or development of electric vehicles. Individuals responsible for development of component design in electric motors, transmissions, suspension and Trims will find this helpful.

Why you should attend?

• Understanding the motor, wind, road and other ancillary noise sources contributing towards Electric Vehicle’s interior noise levels
• E-Motor design from NVH preceptive
• Interior noise simulation for
  - Road-induced vibrations
  - Turbulence induced noise etc.
• Perceived Sound Quality improvement through Squeak and Rattle prediction
• Altair’s advanced offerings for E-Vehicle NVH refinement
