The Complex Dynamical Behaviors of Lateral Vibration of Tire

Article Preview

Abstract:

Considering the nonlinear characteristic of suspension stiffness and the effect of road input, a dynamic model of tread’s lateral vibration is established based on lateral-vertical force coupling, and the complex dynamic behavior of the system is analyzed. The results show that: the lateral self-excited vibration of tread is a kind of complex quasi-periodic motion caused by Hopf bifurcation of system, which oscillating range increases at first, then decreases with vehicle speed; the quasi-periodic motion occurs only at specific speed range, while not happen when speed is too low or high.
