Study on NVH Behaviour of an Electric Hybrid DriveCopyright: © IEM
Electrical drives for automotive applications require a particular focus on the NVH, stands for noise-vibration-harshness, behaviour. Accoustic emissions, caused by force excitations inside electrical machines, can be disturbing for the human hearing. In this project, the acoustic behaviour of a hybrid drive has to be studied. In focus are manufacturing deviations and inverter influences with consideration of conventional tolerances.
