| 中文摘要: |
| 通过对硫化时的轮胎模具上盖进行受力分析，并根据弹塑性力学薄板计算理论，建立上盖受力简化力学模型。利用有限元模拟分析不同结构形式对轮胎模具1188壳体上盖应力和应变的影响。结果表明：增大上盖闭滑板面积可使上盖应力和应变减小；当上盖及上侧板为整体式结构且均采用Q235钢时，上盖的应力小于Q235钢的许用应力，变形量均小于0.05 mm，满足设计要求；上盖与上侧板整体式结构的上盖应力和变形量较小。 |

| Based on the stress analysis of the top cover of the tire mold under curing conditions and according to the elastic-plastic mechanics theory of thin plate，the simplified mechanical model of top cover was established. The effect of different structural forms on the stress and strain of the top cover of tire mold 1188 shell was analyzed by finite element simulation. The results showed that，increasing the area of top cover slide could reduce the stress and strain of top cover. When the top cover and the top side plate were integrated and both were made of Q235 steel，the stress of top cover was less than the allowable stress of Q235 steel，and the deformation was less than 0.05 mm，which met the design requirements. The stress and deformation of top cover with an integral structure of top cover and top side plate were smaller. |
