Multibody Dynamic and NVH Simulation, AVL List Gmbh.
By developing more electric vehicle more and more focus are the noise and vibration from Electric Drive unit. One characteristic sound is the tonal noise from the E-machine. This paper shows first how this tonal noise can be simulated and show the comparison to measurement. Then it shows the effect of current on NVH and the method used by JMAG to simulate the current harmonics.
