Abstract
Starting from the analysis of tire ground contact characteristics, the formulas of ground contact patch of tires are obtained, which are verified by tests, and the calculation formula of lateral stiffness of tread element is determined using the energy method. On this basis, a dynamic model of tread's lateral vibration is established, and the effects of vehicle speed, vertical load and tire pressure are analyzed. The results show that: the lateral self-excited vibration will occur under certain conditions, and vehicle speed, vertical load and tire pressure have great influence on the vibration characteristics; the lateral self-excited vibration of tread is a kind of stable periodic vibration caused by Hopf bifurcation of system.
