Based on a tread-road single degree-of-freedom vibration model, the physical characteristics of the system of suspension, tire and tread were studied, and further a suspension-tire-tread four degree-of-freedom ADAMS vibration model was established in accordance with the multibody dynamics theory. Simulation results show that the energy of vibration will be transferred to suspension and tire when the tread vibrating violently. Meanwhile, the toe-in angle, the camber angle and the vertical beating of tire will also start to fluctuate with the same frequency, however in various extents. The reasonableness of model simplification, and the correctness of the model were thus verified. The numerical simulation of bifurcation was applied on the four degree-of-freedom system, and the vehicle speed range which can generate the self-excited vibration of tire tread was provided. The dynamic differential equations of the model are helpful to further theoretically and experimentally study the nonlinear behaviors of such systems.
