| Abstract: | Damping package is one of the methods to reduce the vibration and noise of the whole vehicle. Adjusting and optimizing the damping package is useful to improve the NVH performance and reduce the cost and weight . In the paper, it puts forward to a method for the vehicle damping package through the vibration analysis. And taking the roof as an example to illuminate method. |
