Abstract:
In this thesis, vibro-acoustic analysis of tire and wheel assembly has been studied using a coupled model of tire, rim, and acoustic cavity and also a coupled model of the acoustic cavity and tire tread using finite element method (FEM). For each of the models, initially modeling of the components is performed using SolidWorks software and are subsequently assembled and coupled. Using ANSYS acoustic and modal modules, analyses are performed to explore the natural frequencies and mode shapes of the corresponding components and the coupled model. Two-way interaction between fluid and structure has been considered. Finally, using the coupled model, the parameters affecting tire noise level are evaluated and modifications are proposed which reduce the noise level substantially.
Keywords: vibro-acoustic analysis, coupled model, acoustic cavity, tire, wheel, rim, ANSYS, finite element method (FEM).
