NVH assessment and optimization in EVs and HEVs

Electrical and hybrid vehicles development open a new field of noise and vibration challenges. First, a quieter cabin environment, relieved from the ICE noise, let new sources emerge. Those sources often generate low sound levels but with unworked sound design, providing consequently a poor sound experience for the passenger. On its side, the main propulsion motor plays a major role in the overall sound: its vibroacoustic behavior can be assessed and improved using the appropriate technology. Globally, E-NVH requires a wide scope of dedicated skills and high-end tools: from simulation to testing. Discover all about it in this presentation!
