Analysis of Influence of Tire Pressure on Polygonal Wear of Tire

摘要

Considering the influence of tire pressure on tire stiffness, a dynamic model of the polygonal wear of tire was established based on the lateral vibration of tire tread, and the dynamical behavior of system was analyzed through numerical simulation. The results show that: the polygonal wear is a typical nonlinear self-excitation vibration phenomenon which is proved to be a kind of stable periodic vibration caused by Hopf bifurcation of system; when tire pressure is inadequate or excessive may lead to polygonal wear of tire.
