| 中文摘要: |
| 传统四立柱式平板硫化机底座采用铸铁材料铸造、底座拉耳处通常采用翻砂口下置式结构，因材料分布不合理、底座拉耳抗拉能力较低，导致出现底座拉耳处断裂的现象。通过常规应力分析与ANSYS建模分析，对比下置式与上置式翻砂口底座拉耳处应力分布规律。结果表明，充分利用铸铁的抗拉能力远小于抗压能力这一特性，将拉耳处翻砂口改为上置式结构，能够有效地改善底座拉耳的受力，防止底座在拉耳处断裂。 |
| 英文摘要: |
| The base of traditional four pillar plate vulcanizing machine was made from cast iron and the pull ring was usually formed under the level of casting gate entry point.Due to the improper distribution of material， the tensile strength of pull ring was low，which resulted in easy fracture of pull ring.In this study，the stress distribution of pull ring was analyzed through conventional stress analysis and ANSYS modeling analysis，considering the cases that pull ring position was under and above the level of gate.The analysis results showed that since the tensile strength of the cast iron was much lower than the compression strength，when the pull ring was formed above the level of the gate，the stress distribution of pull ring was improved and the easy fracture was prevented. |
