| Abstract: |
| 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. |
