Simulation Study on Influence of Tread Pattern on Tire Performance

The finite element models for tires with smooth tread,longitudinal grooved tread and regular patterned tread were established by using ABAQUS software,respectively,and the stress distribution of the three tires in different conditions were analyzed.The results showed that,in static load condition,the Von-Mises stress distributions of three tires were similar,and the end of belt layer had the largest stress.The whole stress level of the tire with regular patterned tread was the highest while that of the tire with smooth tread was the lowest.However,the stress of 1st belt layer of the tire with smooth tread was quite high.Under static load,steady rolling or cornering rolling condition,the high stress areas of the tire with smooth tread were all in the tire shoulder.However,the high stress areas of longitudinal grooved tire and patterned tire were distributed in the tire shoulder and the central part of tire crown in static load and steady rolling conditions;while the high stress concentrated on the edge of the groove in the middle part of the tire tread under cornering rolling condition.
