故障树分析法在系统故障诊断中的应用

Application of Fault Tree Analysis in Fault Diagnosis

在故障诊断的故障树定量分析方法基础上,对最小割集重要度的概念进行了重新定义,引入了故障系数的概念,进一步完善了故障树最小割集用于故障诊断的定量分析方法,并基于结构重要度的概念给出了一种故障树最小割集用于故障诊断的定性分析思路。最后结合实例给出了故障源搜寻的具体可行的测试步骤。

Based on the analysis of fault tree theory, it defines the important degree of minimal cuts set and carries on the concept of fault coefficient. Using the quantitative diagnosis approach for minimal cut sets of fault trees, it presents a method based on the structure important degree of minimal cut sets of fault trees. As an example, it shows the detailed testing step of searching fault origin.
