| 中文摘要: |
| 采用Tekscan轮胎接地压力分布测量系统进行半钢子午线轮胎静态及滚动状态下接地特性的试验研究。结果表明：随着气压的增大，轮胎接地压力分布趋于均匀，最大接地压力值增大，胎肩处应力集中现象有所缓解；随着气压的减小，接地宽度变化不大，但接地长度和接地面积增大。在相同气压条件下，滚动状态下接地特性的评价指标普遍比静态下小。相对于静态条件，滚动状态下轮胎接地压力分布更均匀，胎肩应力集中减小。 |

| The ground contact characteristics of steel-belted radial tire under static and rolling conditions were experimentally investigated by using Tekscan pressure distribution measurement system.The results showed that，with the increase of inflation pressure，the contact pressure distribution of tire became even，the maximum contact pressure increased，and the stress concentration at shoulder was reduced.As the inflation pressure decreased，the contact width changed little，but the contact length and contact area increased.At the same pressure condition，the evaluation index of contact performance of rolling tire was generally smaller than that in the static state.Compared with the static condition，contact pressure distribution of rolling tire was more uniform，and the stress concentration at shoulder was smaller. |
