| 中文摘要: |
| 以11.00R20 18PR全钢载重子午线轮胎为研究对象，利用轮胎专用有限元分析软件TYSYS分析双复合胎侧和三复合胎侧设计方案对胎圈耐久性能的影响。有限元分析结果表明，三复合胎侧设计可以提高轮胎负荷能力/径向刚度，减小胎圈反包区域的应变能变化幅度，从而提高胎圈耐久性能。成品轮胎试验结果验证了有限元分析结果的正确性。 |
| 英文摘要: |
| Based on 11.00R20 18PR truck and bus radial tire，the effect of two-composite sidewall and three-composite sidewall design on bead endurance was analyzed by the finit element analysis （FEA） tire special software TYSYS.The FEA results showed that，using three-composite sidewall design，the tire loading performance and radial rigidity were improved，the varying range of strain energy in the bead turn-up area was decreased，so that the bead endurance of tire was increased.The FEA results were confirmed by the test of finished tires. |
