| 中文摘要: |
| 基于Abaqus和Tyabas有限元分析软件，根据315/60R22.5全钢载重子午线轮胎胎圈实际损坏形式提出结构优化方案，建立有限元模型，并通过增强材料端点区域的应变能密度、Mises应力、剪切应变LE13和LE23分析进行方案优选。结果表明，通过胎圈结构优化，优选方案增强材料端点的应力、应变分布情况显著改善。成品轮胎胎圈耐久性能试验结果与有限元分析结果一致，优选方案轮胎胎圈耐久性能均优于初始设计方案，最优方案轮胎延长胎圈耐久性能试验时间70 h以上，实现了提高胎圈耐久性能的目的，延长了轮胎的使用寿命。 |
| 英文摘要: |
| Based on Abaqus and Tyabas finite element analysis software，the bead structural optimization schemes were proposed，and the finite element models were established according to the actual damage of 315/60R22.5 truck and bus radial tire．The schemes were optimized by the strain energy density，Von Mises stress，shear strain LE13 and LE23 analysis in the end area of the reinforcement material．The results showed that the stress and strain distribution in the end of the reinforcing material of the preferred solution was significantly improved by the bead structure optimization．The bead endurance test results of the finished tire were consistent with the finite element analysis results，and the bead endurance performance of the preferred solution was better than the initial design solution，and the optimal solution prolonged the bead endurance test time by more than 70 h，which achieved the purpose of improving the bead endurance and extending the tire service life. |
