実路面モデルを用いたタイヤの転動シミュレーション

抄録

Since the tire is driven by frictional contact with road surfaces, the contact condition between tire and road is a very important factor for the tire performances. Conventionally, the finite element analysis is used for predicting or evaluating the tire performances, such as the tire cornering force, traction and breaking forces, that road models is constructed by a flat surface. However, considering of tire rolling on real road surfaces, it is difficult to predict or evaluate tire performances by using a conventional flat surface road model because typical real road surfaces are rough conditions and the grip force of the tire is caused by contact between rough road surfaces and the tire tread rubber. In this study, to evaluate the contact conditions between the tire and the road surfaces constructed by based on real road surface measurement data, the dynamic tire rolling simulation is carried out by a general purpose finite analysis software Ansys LS-DYNA.
