Analysis of Vehicle Interior Low-Frequency Noise Based on ATV

Abstract:

The FEM model of the body and acoustic cavity are created, and the acoustic-structure coupled system is built up,and the SPL(sound press level) of points corresponding to the drivers ear and passengers ears were calculated using software LMS.virtual.lab. And there are several relatively noticeable acoustic pressure peaks around 60Hz, 102Hz, 120Hz and 168Hz. The maximum noise value was calculated by using the method of ATV method, several suggestions are advised to decrease the vehicle interior noise so that the vehicle ride comfort could be improved.
