Characterization of Air-Borne Noise of Shock Absorber by Using Acoustics Index Method

Research interest in vehicle NVH to improve riding comfort has increased significantly in the recent years. The air- and structure- born noise generated by the automotive shock absorber become a key factor to evaluate quality of vehicles. The ultimate goal of this study is to create a vibro-acoustic model of a shock absorber which can be used as a predictive tool by design engineers in the early stage of shock absorber design process. The efficiency of CAE tools developed in this study may also allow for more design iterations and alternatives within a relatively shorter design time, which may lead to a higher level of refinement and better-optimized design
