Noise-Vibration-Harshness simulation of ultralight vehicle traction drives based on a universal modelling approach

This paper advances a system-simulation based universal modelling approach for NVH-simulation of electric drives. The main idea is to use commercial FE-tools for model order reduction and implement generic reduced electrodynamic and acoustic models in a system-simulation environment. Thus FE-tools are reduced to model parametrisation. The NVHcalculation itself is done in a system-simulation framework, which can be easily coupled with control and machine models for electric drives. As a first example, this is performed for an ultralight vehicles' traction drive.
