| 摘 要： | 为拟制大方坯连铸机的拉矫机主压下油缸的连接螺栓频繁发生断裂失效，根据该油缸的连接固定结构以及工作载荷特征，利用有限元数值分析方法对其进行等比例三维仿真分析，并依据分析结果提出了一系列针对性的改进方案。依据该改进方案进行改造的油缸在现场进行使用后发现，该油缸性能稳定可靠，没有再次发生类似的断裂事故。本次对油缸的改造分析，为类似液压油缸的载荷能力分析提供了一套科学合理的分析方法。

| Abstract: | To prevent the bolts of main cylinder for straightening equipment always broken, the loads of cylinder has been studied detailed, and the main cylinder has been analysised by 3D FEA soft. Depending on the resuits of FEA model, the paper has given a lot of reconstructing plan. Then the reconstructed main cylinder has been installed on the stretcher leveller, after these months, it still work safety. This reconstructing analysis of the straightening main cylinder has given a good reference for similar equipment. |
