Evaluating of E-Vehicle Gear Noise

E-mobility role will be increasing in the next decades, and it has fundamentally different approaches than previous technologies. The aim of this research was to set up a measurement system for the evaluation of the gear noises of a premium vehicle. The measurements showed that with the use of a fast and simple instrumentation, a detailed sound analysis can be created, if the right measuring and analysis system is used. During the acceleration phase, the dominant gear mesh orders at the outside of the vehicle were almost inaudible.
