Abstract : To predict, analyze and optimize the low frequency noise of a Chinese vehicle, a structural- acoustic coupling finite element model was established. The excitation signals at the suspension mountings and engine mountings, and the responding signal of the interior noise were measured with road testing. Appling the excitation signals to the structural-acoustic coupling model, the frequency response analysis was carried out and the low frequency noise was calculated. The simulation response of noise was compared with the result of testing. The consistency between the simulation and testing result
