The optimal layout of damping materials plays an important role in vibration and noise control of vehicle inside. The body in white( BIW) of a certain car was studied here. Based on the finite element method and boundary element method,the acoustic field inside the car and the panel contribution to the vehicle were analyzed. Then,the peak frequencies in the sound pressure spectrum at the field points and their corresponding panels with larger contributions to the car were found. Based on the modal analysis of the BIW,the layout of the constrained damping materials was optimized. The noise responses inside the car to the excitations at the engine mount,front suspension and rear suspension were analyzed before and after the damping optimization,and then the validity of this technique was verified. The results of the actural car tests showed that after adding the optimized damping material layout on the vehicle body,the interior noise of the vehicle reduces 2d B( A).
