Analysis of Tire Cornering Stiffness Property under Slight Driving or Braking Condition

Abstract:

A tire model considering the lateral and longitudinal stiffness of carcass was built to describe tire cornering stiffness property under slight driving or braking condition. The effects of carcass elastic on the tire cornering stiffness were analyzed by varying carcass stiffness. Analysis shows that tire cornering stiffness have a strong relationship to the tire carcass stiffness and the tire longitudinal force. Tire cornering stiffness increases with the increase of carcass bending stiffness and torsional stiffness. And tire cornering stiffness increases with the increase of the braking force if the carcass translation stiffness in the longitudinal direction is far more than that in the lateral direction. When carcass translation stiffness in the longitudinal direction is equal or less than that in the lateral direction, tire cornering stiffness decreases with the increase of the braking force.
