The present thesis addresses the vibroacoustic performance prediction of an electric drive unit developed by Garrett for battery electric vehicle applications. This is a relatively young and developing topic in the engineering literature, with limited research available. The high competitiveness of the BEV market renders the powertrain’s vibroacoustic performance a distinctive advantage among carmakers and OEMs, often protected by intellectual property. Most analyses are based on testing and empirical measurements rather than on a rigorous theoretical procedure. The methodology employed to build a complete simulation, from evaluating the electromagnetic loads of the electric motor to predicting the radiated noise, is extensively discussed in Chapter 3.
