| 应用Abaqus有限元模拟软件对硫化工况下的轮胎模具底座进行热力耦合和力学性能分析；应用Fe-Safe软件对不同厚度和滑板结构的底座进行疲劳损伤和使用寿命计算。结果表明：轮胎模具底座的最大应力出现在U形螺栓槽处，最大位移出现在与U形螺栓槽成45°的圆周边缘；底座应力与底座厚度和滑板面积成反比；下侧板连接形式对底座应力和位移影响不大；底座最先破坏的部位为U形螺栓槽附近，增大底座和U形槽厚度可以延长其使用寿命。 |

| The thermodynamic coupling and mechanical property analysis of the tire mold base during vulcanization were carried out by the finite element simulation software Abaqus，and the fatigue damage and service life of the base with different thickness and sliding plate structure were calculated by software Fe-Safe .The results showed that the maximum stress of tire mold base occured at the U-shaped bolt groove，and the maximum displacement of the base occured at the circumferential edge of 45 degrees with the U-shaped bolt groove.The stress of the base was inversely proportional to the thickness of the base and the area of the sliding plate.The connection form of lower side plate had little effect on the stress and displacement of the base.The first place where the base was damaged was near the U-shaped bolt groove，the thickness of the base and U-shaped groove could be increased to lengthen its service life. |
