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...
Simplifying the tread-road model, a finite element model of the tire tread lateral self-excited vibration using LuGre friction model is established in MSC.Marc. With the finite element model, the lateral self-excited vibration of tread is simulated and analysed. Spectral analysis of the vibration signal is carrid out as well. At last, the influence of vehicle speed on lateral self-excited vibration...
Because of self-oscillation of tire, Polygonal Wear occurred on the tire which often rolled on freeways or highways. With the intention of researching suspension's effect on the self-excited vibration of tire, according to the characters of polygonal wear, the twist beam suspension of car PassatB5 was simplified to proper mechanical model in the method of FEA. Then, making the coupling of lateral...
This work explains the hopf bifurcation and stability of self-excited vibration with the variety of vehicle velocity. Polygonal wear of tire is one of the most pressing problems to be solved in the process of a vehicle's research and design. Based on the non-linear character of friction coefficient, which combines the concept of static and kinetic friction, a model of tread-pavement, taking time-delay...
The intention behind this work is to develop a friction coefficient model understanding of self-excited vibrations. As a result of self-oscillation, Polygonal Wear often occurred on the tire of truck/bus and car which run on freeways or highways continuously. Based on the characters of Polygonal Wear, we showed a mass-on-moving-belt frictional vibration model, which reflected the phenomenon of lateral...
