Abstract :
A dynamic vibration model of suspension-tire-tread four degree-of-freedom theoretical vibration model, taking time-delay into account, is established to study the range of speed to motivate self-excited vibration and the relationship of vibration character and speed. The numerical simulation of bifurcation is applied to the four degree-of-freedom system, and the vehicle speed range which can generate self-excited vibration of tire tread is found. The dynamic differential equations in the theoretical model can be used to further research.
