Avoid NVH issues in electric vehicles by using the source-transfer-receiver methodology

Powertrain electrification is one of the key enablers for the future automobile industry to reach lower CO2 emission targets. Although electric vehicles are significantly quieter than vehicles with an internal combustion engine (ICE), they bring their own noise, vibration and harshness (NVH) challenges. 

This whitepaper describes how to address complex NVH problems by breaking each issue into source-transfer-receiver components. Using this methodology helps to identify the root causes of late design issues and offers the possibility to implement design changes later on.
