ABSTRACT
In this paper, particle dampers were pasted on the model car which was made from thin steel plate. Sound pressure of the field points inside the model car were obtained by vibration-acoustic coupling simulation and acoustic experiment separately. The acoustic simulation model of the model car with particle dampers is validated through the contrast of the simulation results and experimental data. On the basis, the difference of sound pressure inside the model car were studied which was pasted by particle dampers at different positions. The research will provide a good reference for the application research of the thin-walled car body with the particle damping.
