摘　　要：采用故障树分析法,将提梁机液压卷扬系统所发生或将要发生的故障作为故障树顶事件,将系统故障发生的原因分级组成故障树的各级中间事件和底事件,并且求出导致顶事件发生的最小割集,依此对故障树进行定性分析,从而解决引发顶事件的底事件,发现和排除系统故障。By using fault tree analysis, seeing the fault occurred or would be occurred of the hydraulic winch control system as fault tree top events, the causes of system fault were graded, and seen them as intermediate and bottom events. Then the minimal cut sets were found which caused top events to occur. According to this, qualitative analysis to fault tree can be conducted, and the bottom events are found which caused the top events, and detected and excluded the system fault.
