Abstract
Low-frequency interior noise is important contents for improving the NVH quality of vehicles. Prediction and reduction of the major sources of low-frequency noise have important significance for noise control. In this paper, the low-frequency interior noise was predicted by using the method of ATV. The frequency response function of the field point was obtained, and the contributions of the panel to the field point were analyzed. Modal contributions of the body structures were obtained by using the method of MATV, and the body structure which has large contributions of sound pressure to the field point was predicted according to the modal results. The interior low-frequency noise was reduced in some extent after the improvement of the body structure. This work has provided a theoretical reference for reduction of interior noise of vehicles.关键词
