摘　　要：以185/75R14电动汽车半钢子午线轮胎为研究对象,分别建立含纵沟花纹和含复杂花纹轮胎的有限元模型。利用磨耗后处理法的数值求解策略,研究在制动工况下滑移率对轮胎胎面磨耗行为的影响。结果表明,在相同的行驶速度下,制动轮胎胎面的磨耗速率随着滑移率的增大而剧烈增大,含复杂花纹轮胎胎面出现了纵向和侧向的不均匀磨耗,其胎面的磨耗速率明显大于含纵沟花纹轮胎胎面。Taking the 185/75R14 electric vehicle steel-belted radial tires as the research object,the finite element models of the tire with longitudinal groove patterns and the tire with complex patterns were established respectively.Using the numerical solution strategy of the wear post-processing method,the influence of the slip rate on the tread wear behavior of the tire under braking condition was studied.The results showed that under the same driving speed,the tread wear rate of the braking tire increased drastically with the increase of the slip rate.The tread of the tire with complex patterns had uneven longitudinal and lateral wear,and its wear rate was significantly greater than that of the tire with longitudinal groove patterns.
