| Abstract: |
| 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. |
