| 中文摘要: |
| 以215/55R17子午线轮胎为研究对象，对轮胎进行实车磨耗测试，在初始磨耗阶段中间花纹沟存在磨损较快现象。基于摩擦能理论，结合轮胎实际工况，建立考虑复杂花纹的数值分析模型，得到的胎面摩擦能分布与实际磨耗测试结果一致性较好。同时建立具有3种横沟加强筋和3种横沟深度的花纹模型，分析不同花纹横沟加强筋和花纹横沟深度对胎面摩擦能分布的影响，结果表明，数量较多的花纹横沟加强筋可有效改善胎冠中心花纹块的耐磨性能；较浅的花纹横沟可以有效降低花纹块中间区域的摩擦能，但是花纹块摩擦能分布均匀性较差。 |

| 215/55R17 radial tire was taken as the research object，the real vehicle wear test was carried out on the tire，and there was rapid wear in the middle groove in the initial wear test stage.Based on the theory of friction energy，a numerical analysis model considering complex tread patterns was established in combination with the actual tire working conditions，the distribution of friction energy on the tread was in good agreement with the actual wear test.At the same time，a pattern model with three kinds of crossed groove reinforcing ribs and three kinds of crossed groove depths was established，and the influences of different crossed groove reinforcing ribs and crossed groove depths on the distribution of tread friction energy were analyzed.The results showed that a large number of crossed groove reinforcing ribs could effectively improve the wear resistance of the central pattern block of the tire crown；shallow cross grooves could effectively reduce the friction energy in the middle area of the pattern block，but the distribution of friction energy in the pattern block was poor. |
