摘　　要：目前自动扶梯的应用广泛,极大的方便了人们的出行,但却也出现了很多的事故,其安全方面存在的隐患越来越受到重视,所以将灰色关联分析方法引入自动扶梯故障树分析中,建立了自动扶梯故障树,根据故障树中底事件的结构重要程度,对故障树中各个故障因素发生的可能性大小做出准确判断。用实例来说明这个方法,实例结果表明:支架盖断裂是影响自动扶梯可靠性的主要因素,为快速判断自动扶梯的故障、保障人们的生命安全提供了一种有效的方法。At present,the wide application of the escalator is greatly convenient to people’s travel,but a lot of accidents arise.The hidden danger of its security is paid more and more attention.So the grey relation analysis method is applied in the analysis of the fault tree of the escalator.The escalator fault tree is also be established.Based on the importance of the bottom event in fault tree,the happening possibility distribution of fault factor in the fault tree is judged quickly and correctly.A practical example is used to illuminate this method,the results in the practical example show that:Bracket cover fracture is the main factor affecting the reliability of the escalator.It provides an effective method to quickly judge the escalator failure and protect the life safety of people.

关 键 词：自动扶梯 安全 灰色关联分析 故障树 可靠性 有效
