| 中文摘要: |
| 设计具有不同纵沟、横沟、沟槽角度和深度的胶块来模拟轮胎的胎面花纹，使用便携式摩擦试验机对胶块进行磨耗试验，通过有限元仿真计算胶块的纵向刚度，分析胶块纵向刚度与磨耗性能的关系。结果表明：通过沟槽数量和方向等因素改变花纹块刚度时，磨耗量随纵向刚度的增大而减小；通过沟槽深度改变花纹块刚度时，磨耗量随纵向刚度的增大而增大。 |
| 英文摘要: |
| The pattern structure of a tire has a significant impact on its wear resistance. In this study, rubber blocks with different longitudinal grooves, transverse grooves, angles, and groove depths were designed to simulate tire tread patterns. The wear experiments of the rubber blocks were conducted using a portable friction tester. The longitudinal stiffness of the rubber blocks was calculated using finite element simulation. The relationship between the longitudinal stiffness and wear performance of the rubber blocks was analyzed. The results show that when the pattern block stiffness is changed by the number of slots, transverse and longitudinal slotting, and slotting angle, the wear volume decreases with the increase of longitudinal stiffness. However, when the pattern block stiffness is changed by slot depth, the wear volume increases with the increase of longitudinal stiffness.The rubber blocks with different longitudinal grooves，transverse grooves，groove angles，and depths were designed to simulate the tire tread pattern.The wear tests on the rubber blocks were conducted using a portable friction testing machine，the longitudinal stiffness of the rubber blocks was calculated through finite element simulation，and the relationship between the longitudinal stiffness of the rubber blocks and their wear performance was analyzed.The results showed that when the stiffness of the pattern block was changed by factors such as the number and direction of grooves，the wear amount decreased with the increase of longitudinal stiffness，and when the stiffness was changed by the depth of the groove，the wear amount increased with the increase of longitudinal stiffness. |
