Abstract

Abstract: Transfer path analysis (TPA) method is utilized to identify and optimize the transfer path of tire cavity noise in vehicle in this paper. Firstly, a TPA model for vehicle interior noise is set up, based on which the transfer paths with dominant contributions to tire cavity noise in vehicle are found out. Then through CAE simulation, the components, which need to be optimized, on those transfer paths is determined with optimization scheme proposed. Finally, the optimization scheme is validated by test. The results show that the optimization scheme proposed can well suppress the tire cavity noise in vehicle, verifying the feasibility and effectiveness of TPA method in optimizing the tire cavity noise in vehicle

Key words: tire cavity noise; transfer path analysis; contributions; transfer path optimization
