Wheel dynamic response to rolling excitation on road

In this paper, tyred wheel dynamic response to road excitation during rolling has been simulated using finite element modelling in a graphical programming environment. The actual contact is an area not a single line and the contact edges are subject to continuous impacts during the rolling. The structural response to the impact generates structure borne noise as part of pollution to the environment. To reduce the wheel noise can be achieved by attenuating the intensity of structural vibration. The relationship between the noise generation energy of wheel and damping is investigated. It is proposed to reduce the noise by increasing the damping in the tyre structure. The effectiveness has been demonstrated by the simulation result.
