Summary:

As the technology is growing and the development of electricvehicles is advancing, though there are advancements in technology,an automobile will always have the challenges of Noise, Vibration,and Harshness. With several years of study and research, variousmethodologies have been developed for the refinement of NVH inconventional vehicles (IC engines). But in terms of BatteryElectric vehicles (BEV), we have new areas to explore to refineNVH. Currently, in the competitive market, developing a fullyground-up Electric vehicle is a challenge due to the aggressiveproduct development timelines and high cost of development. As aresult, many OEMs are considering to convert their Conventionalexisting vehicle to Battery Electric vehicles as they will needlesser product development timelines with their Go to marketstrategy. This Paper is focused on virtual NVH validations whileconverting an existing conventional vehicle body architecture tomake it to a pure Battery-operated Electric Vehicle architecture.This is accomplished by replacing the conventional powertrainsystems and associated ancillary components with new Power andEnergy systems on BEV. Architecture changes of the vehicle bodyneed to be evaluated at various stages of vehicle development likeBIW, Trimbody and Full vehicle as there may be a significantchange in vibration transfers and Noise transfers because of bodyMass and stiffness changes. The structure-borne contributions fromRoad input in BEV at Full vehicle level are dominant, Tactile andAcoustic responses at Driver location are evaluated and discussedin this Paper
