| 采用有限元分析软件ANSYS对特大型密封圈注射硫化机箱式梁结构进行优化。结果表明：与无肋板箱式梁相比，有肋板箱式梁的应力降低，形变减小；有肋板箱式梁的应力集中于中间两个支撑柱孔处且超出许用应力，在支撑柱孔处采取倒圆角处理可以降低应力集中现象；正交试验表明，上横梁壁厚为35 mm、肋板宽度为40 mm、上横梁高度为410 mm时，上横梁承受的应力最小；与结构优化前相比，结构优化后的上横梁应力小于许用应力，形变变化不大，有利于延长特大型密封圈注射硫化机箱式梁的使用寿命，减小整机质量并降低制造成本。 |
| 英文摘要: |
| 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. |
