Methods and Solutions for the Integration of the HV Battery into the NVH Development of a BEV,f vehicles. With the development of specific vehicle platforms for electric cars, NVH strategies and technologies may strongly change and with them the challenges for NVH engineers..The integration of the battery pack system in the vehicle is steering the focus towards an “integrated” design of the

Measurement of Transfer Matrices of Polyurethane Foam Materials for Sound Absorption and Transmissiive applications. A challenge for developing new acoustic materials is to have a reliable, reproducible and representative small-scale measurement technique to obtain acoustic properties of polyurethane foam. In this paper we present a new measurement technique, based on an impedance tube, where the

This includes the determination of critical noise rating drivers and propagation of noise to the driver’s ear through several vehicle tests. However, early in development, vehicles are not easily ava
