摘　　要：大型液压机的横梁由于铸造、加工、运输等原因,大多设计成组合结构,采用预紧螺栓组连接。通过液压机的两种工况,对下横梁进行受力分析,并进行了连接螺栓组的设计计算。For the convenience of casting, machining, transporting, etc, the beam of large-scale hydraulic forging press has always been designed as combined structure and connected with pre-stress bolts. According to two different working situations of the hydraulic forging press, the paper carries out the stress analysis of lower beam, then calculates and designs the connecting bolts.

关 键 词：组合下横梁 下横梁半梁 预紧螺栓组 中性轴
