| 中文摘要: |
| 利用有限元分析方法对385/65R22.5轮胎进行轮廓优化设计。增大轮胎行驶面和带束层宽度及胎肩内轮廓的曲率半径，可有效降低带束层端部的应力集中程度，同时明显改善轮胎的接地形状和接地压力分布。成品试验证明，优化设计轮胎的耐久性能和高速性能明显提高。 |
| 英文摘要: |
| The 385/65R22.5 tire profile was optimized by FEA.The stress concentration at belt ends of optimized tire was effectively lowered，and the shape of ground-contact area and the pressure distribution in ground-contact area improved significantly by increasing the widths of running face and belt.It was confirmed by the test of finished tire that the endurance and speed performance of optimized tire improved significantly. |
