| Abstract: | Spectrum analysis technique is used to analyze the component of internal noise of vehicles, and modal analysis is applied to analyze the vibration of vehicle＇ s body. The damping panels are applied to control the interior noise of the vehicle and their positions in the vehicle are determined. It is verified by experiment that damping panels can effectively inhibit vibration of the vehicle＇s body and reduce the internal noise in the vehicles. |
