摘　　要：介绍了故障树分析法。阐述了地铁列车牵引建立的条件。以地铁列车牵引系统为例,建立了故障树并求得最小割集。基于最小割集和故障案例统计数据,对故障进行了诊断。此分析方法在地铁列车故障诊断中有较好的应用价值。The fault tree analysis method is introduced, in whichthe conditions of traction establishment in metro ve- hicleare elaborated. By taking the metro traction system as an example, the fault tree is constructed and the minimal cut sets are computed. Based on the minimal cuts and the statistical data of failure cases, faultsaredetected. This method is simple and practical with good applicable value in fault diagnosis of metro vehicles.
