摘　　要：文章分析了循环氢压缩机连杆螺栓断裂原因,主要为某次安装过程中连杆螺栓的打压值超出材质本体的疲劳强度,运行过程中连杆螺栓承受交变载荷本体缩颈部位出现疲劳裂纹直至断裂情况的发生。The knock-down value of connecting rod bolts exceeds the fatigue strength of the material body during one installation.Fatigue cracks appear in the necking part of the connecting rod bolts subjected to alternating loads until the fracture occurs during operation.

关 键 词：连杆螺栓 应力分析 形貌分析
