Abstract :
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 friction self-excited vibration of tire and draw-wrest operation of lengthways pendulum arm taking the previously built friction coefficient model into account which could cause the self-excited vibration of tire, a three degree-of-freedom dynamic modeling of twist beam suspension-tire system was built based on the self-oscillations of tire.
