摘要
故障树法是利用事件符号、逻辑门符号和转移符号绘制成"树"状因果关系来分析和描述事故故障,是重要且很有前途的故障分析方法。基于故障树法,首先阐述其概念和建立的方法以及对故障发生概率的计算方法,然后以一起电梯作业人员进入轿顶发生的电梯剪切事故为案例构建故障树展开分析。
Fault tree analysis(FTA) is an important and promising fault analysis method, which uses event symbols, logic gate symbols and transfer symbols to draw a tree-like causality to analyze and describe accident faults. Based on FTA, the concept and method of establishing the fault tree and method of calculating the probability of fault occurrence are firstly introduced. Then, a case of an elevator shearing accident when elevator operators enter the car roof is taken as an example to construct the fault tree for analysis.
