Abstract：In order to enhance the noise,vibration,and harshness(NVH)performance of the interior body structure of electric vehicles,a finite element model of the interior body structure of a certain electric vehicle is established based on the ANSA platform.Typical excitation points are scientifically positioned,and the peak response of the vibration transfer function(VTF)at key response points(seat mounting points,steering wheel)is simulated and analyzed.The simulation results show that the peak VTF values at each response point meets the design requirements,and the interior structure exhibits good attenuation effect on vibration transmission under the current layout and connection conditions.This research provides technical support for the virtual verification of NVH performance of electric vehicle bodies and holds significant engineering application value.
