Finite Element Analysis on Contact Performance of Radial Tire with Tread Pattern

A three dimensional tire finite element model with tread patterns was established by using Abaqus software,and the contact performance of tire under different conditions were studied. The results showed that,the stress distribution of tire under static loading and free rolling conditions were similar,which was symmetric along the central line of the tire tread,and the maximum stress located in the shoulder of tire.On the driving condition,the high stress area extended towards the opposite direction of movement,while it extended towards the same direction of movement under the braking condition.The stress distribution of tire on a slope was similar with free rolling;however the maximum stress was higher.Under lateral rolling,the stress was mainly located in the central part of the tire tread and the side along the lateral direction,and the stress level increased significantly.
