| 中文摘要: |
| 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。 |
| 英文摘要: |
| Simulated analysis of lateral relaxation length of 215/60R17 96H DH16S passenger car radial tire 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）]，lateral relaxation lengths of different tires could be obtained，and Method 2 results had a higher degree of agreement with the experimental results.As the increase of the load，the maximum lateral force and lateral relaxation length of the tire both increased.As the increase of the inflation pressure，the maximum lateral force of the tire changed little，and the lateral relaxation length of the tire decreased. |
