Abstract: The tyre cavity resonance induced noise and vibration currently have no effective mass production solutions. All proposed solutions are hard to service and difficult to maintain. Different analysis approaches are presented in this paper to verify computer simulation models. Modal analysis results of the tyre cavity, tyre and rim structures were compared and a complex nature of tyre cavity acoustics is understood. Modified air cavities have been simulated. The research in this paper aims to find effective solutions for elimination of the coupled resonance mode by shifting the tyre cavity modal frequency.

Keywords: tyre cavity resonance; modal analysis; resonance induced noise; fluid-solid coupling resonance; vehicle noise; vehicle vibration; simulation; modelling; wheel rims; tyre cavity acoustics; modal frequency.
