Dynamic response of center of the wheel riding on multi-layer road is simulated.Firstly discrete roughness data of road is created in matlab according to the data of various layers of roads.Secondly the data is transferred to create the key points in ANSYS,and so the top layer is created.Subsequently the next four layers of the road are created.Plane model is used for the tire.LS-DYNA is used to calculate the acceleration response of the center of the tire.The simulation result shows that,elastic road buffers the pressure of the vehicle relative to rigid road.And it also suggests that accelera...
