Abstract

The application of acoustic materials is not only an important method of improving NVH performance of vehicle, but also the main work of acoustic packaging. The improvement effect of high-performance acoustic materials on vehicle NVH performance is discussed in this paper. Through experimental data this subject research different influence on NVH performance with three type material, including acoustical material, acoustic insulating material and damping material, and with variety of material or different specification, so that will helpful for selection material. Two solutions of different materials are obtained based on different application positions and materials combination. And then the effect is evaluated on the vehicle. The effects of two solutions are compared with the original vehicle’s performance. The influence of material performance and application position difference on the NVH performance of vehicle body is also studied. The objective of this study is to provide reference for development on performance of material package.
