Project

Acoustic modelling and testing of electric vehicle drivetrains

The aim of this PhD project is to develop methods to predict the structure borne noise transmission and the overall sound pressure level at the driver’s ear in future electric cars. The prediction includes the transmission of the structure borne noise from the excitation from the electrical drive train (electromagnetics and gear whining noise), through the elastomer mounts and the chassis to the driver’s ear. Various FRF’s (frequency response functions) describing the dynamic behaviour of different subsystems of the vehicle are coupled using dynamic subtructuring to predict the vehicle behaviour. The PhD thesis will improve the methods themselves (such as a higher frequency range, simulation of rubber mounts or mechanical acoustical transfer function of the car body) as well as apply them to derive a better understanding of structure borne electrical drive train acoustics.
