摘要
故障树分析法(FTA)是一种自上而下的分析方法,它是通过事件表示符号、逻辑门符号和转移符号来描述系统中各种事件之间的因果关系。从而编写出的逻辑关系因果图。其目的是查明导致顶层事件发生的原因或原因的组合。本设计通过对搜集的故障实例以及相关资料的分析、归纳编写关于汽车电器电路典型故障的故障树,分析了汽车典型的电器与电路的故障。根据汽车电器电路的诊断实例编写诊断工艺流程,即故障流程图。便于典型的车辆电器设备和电路的故障诊断与排除。
The method of fault tree analysis(FTA)is a method of top-down,it is through the event symbols,logic gate symbols and transfer symbols to describe the causal relationships between the various events in the system.Thus draw the logic causality diagram.Its purpose is to find out the cause or causes of combination of top event.Analysis,the design through a case of fault on the collection and summary of the data drawing fault tree about typical fault auto electric circuit,analysis of typical vehicle electrical circuit fault.According to the diagnosis of auto electric circuit to write diagnostic process,namely:the related flow chart.Fault diagnosis and troubleshooting for the vehicle electrical equipment and circuits of typical.
