Simulation and Experimental Validation of Sound Field in a Rotating Tire Cavity Arising from Acoustic Cavity Resonance

As we all know, the tire acoustic cavity resonance noise (TACRN) can cause irritating in a vehicle, but it is evidently difficult to be weakened. To obtain accurately characteristics of TACRN key step attenuating TACRN. In this paper, simulation method, which simplified finite element model automobile with introducing rotation established, proposed gain sound field rotating tire. And test pressure also performed validate method. The comparisons between and experimental consequences show satisfying conclusion. Furthermore, influence factors speed, inflation load on are calculated analyzed.
