| Abstract: |
| The structure optimization of the box beam on injection vulcanizer for super large sealing ring was studied by finite element analysis software ANSYS. The results showed that，compared with the box beam without ribs，the box beam with ribs could reduce the stress and deformation. The stress of the box beam with ribs was concentrated on the middle of the two supporting column holes and was higher than the allowable stress. The concentrated stress could be reduced by using fillets at the supporting column holes.According to the orthogonal test，the stress of upper beam was minimized when the upper beam thickness was 35 mm，rib width was 40 mm and the upper beam height was 410 mm. After the structure was optimized，the stress of upper beam was less than the allowable stress，and the deformation changed little，which was helpful to extend the service life of the injection vulcanizer for super large sealing ring，and reduce the whole machine mass and manufacturing cost. |
