ゴム摩擦係数の圧力，速度依存性とタイヤ性能への影響

抄録

Friction coefficient of rubber is known depending on pressure and slip velocity. The dependency is measured by laboratory tests using rubber sample. Obtained data are fitted and used for finite element tire simulationthe effect of the dependency compared by constant friction coefficient. Comparison shows that slip s. Tire driving, braking and cornering simulations are carried out to look into velocity dependency makes braking force decrease at larger slip ratio, and pressure dependency makes cornering force decrease at larger slip angle with larger load. Under large slip ration, slip velocity deviation in thpressure deviation in there is confirmed. More sophisticated friction model for rubber is expected for e tire footprint is confirmed, and under large slip angle and larger load, contact tire performance prediction on different road surfaces.
