摘　　要：对215/60R17 96H DH16S轿车子午线轮胎进行侧向松弛长度的仿真分析。结果表明:采用两种仿真方法[对轮胎与轮辋同时施加瞬时侧偏角(简称方法1)和仅对轮辋施加瞬时侧偏角(简称方法2)]可以得到不同的轮胎侧向松弛长度,方法2结果与试验结果的吻合度更高;随着负荷的增大,轮胎侧向力的最大值和侧向松弛长度均增大;随着充气压力的增大,轮胎侧向力最大值变化不大,侧向松弛长度减小。A simulation analysis of the lateral relaxation length of 215/60R1796H DH16S passenger car radial tires was conducted.The results showed that using two simulation methods[simultaneously applying instantaneous sideslip angle to the tire and rim(referred to Method 1)and only applying instantaneous sideslip angle to the rim(referred to Method 2)],different lateral relaxation lengths of tires could be obtained,and the results of Method 2 were in better agreement with the experimental results.With the increase of the load,both the maximum lateral force and lateral relaxation length of the tire increased.With the increase of the inflation pressure,the maximum lateral force of the tire changed little,and the lateral relaxation length of the tire decreased.
