QUANTIFYING THE NVH IMPACT OF COMPOSITE MATERIALS IN EV STRUCTURES: A COMBINED PHYSICAL TEST AND SOUND QUALITY DEMONSTRATION APPROACH

Vehicle weight reduction is important to improve the fuel mileage of Internal Combustion Engine (ICE) vehicles and to extend the range of Electric Vehicles (EVs). Glass Fiber Reinforced (GFR) Composite (Polyamide) brackets provide significant weight reductions at a competitive part price. The key to integrating composite brackets into the vehicle design is to perform adequate analysis to ensure that the noise and vibration performance at the vehicle level meets expectations, while considering frequency, stiffness, and isolation implications. In this paper, case studies are presented for two different vehicles – a Clevis bracket for an IC Engine vehicle, and an electric motor mount bracket. For each case, measurement data is used to develop simulator models which were used for immersive comparison of incumbent and alternate parts.
