| 中文摘要: |
| 研究三角胶高度对轿车子午线轮胎接地特性、刚性和滚动阻力的影响。结果表明，三角胶高度减小，轮胎的接地面积呈增大趋势，纵向刚性和横向刚性呈降低趋势，变形向胎侧转移，滚动阻力系数有不同程度的减小。 |
| 英文摘要: |
| The effect of appex height on the grounding characteristics，stiffness and rolling resistance of passenger car radial tire was investigated.The results showed that as the appex height decreased，the area of tire ground footprint increased，while the longitudinal and transverse rigidity decreased.The deformation shifted to the sidewall，and the rolling resistance coefficient decreased in varying degrees. |
