| 中文摘要: |
| 利用有限元分析方法对425/65 R22. 5 轮胎轮廓进行优化设计。通过有限元优化分析,增大轮胎行驶面宽度和胎冠弧度曲率半径以及胎冠弧高度,适当降低断面水平轴位置,可有效降低轮胎冠部应力集中程度 , 同时带束层由4层结构改为3层带束层加2层0°带束层结构,可明显改善轮胎的接地形状和接地压力分布。成品试验证明 , 优化设计后轮胎的耐久性能和高速性能有明显提高。 |
| 英文摘要: |
| The 425/65 R22.5 tire profile was optimized by FEM. The tress concentration at belts ends was effectively reduced, by increasing the widths of tread running surface, radius curvature and height of tire crown, and lowering section horizontal axis appropriately. Meanwhile, The shape of ground- contact area and the pressure distribution in ground- contact area improved significantly ,by changing belt structure from 4 layers to 3 layers with belt 0。It was confirmed by the test of finished tire that the endurance and speed performance of optimized tire improved significantly。 |
