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...
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...
The three-dimensional finite element (FE) model of the radial tire was built in the software of MARC. In the FE model of tire, the complexities of material and structure, the friction between the tire and the ground, are fully taken into account. Different rolling conditions were simulated under the standard pressure and rated load. The friction stress distribution characteristics of the tire surface...
It can improve the stability of the vehicle by using non-linear spring, such as barrel-shaped helical spring, in vehicle suspension. The barrel-shaped helical spring on the rear suspension of PASSAT B5 was analyzed is this paper. Firstly, the accurate physical model of the spring is built by 3D scanning and post-process. Then the stiffness of the spring was calculated by finite element analysis, and...
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...
