基于故障树的地铁车辆客室自动门系统可靠性分析

Reliability Analysis of Auto Passenger Door System in Metro Vehicle Based on Fault Tree

利用FTA方法对地铁车辆客室自动门系统在运行中错误打开的故障进行了系统的研究,建立了客室自动门系统的故障树,并对故障树进行了定性和定量分析,为提高系统的可靠性和优化门系统设计提供了依据。

This paper studies systematically with FTA method faults of auto passenger door system opening by mistake with metro vehicle operation,and constructs a fault tree of auto passenger door.It also makes a qualitative and quantitative analysis of the fault tree,which supply a basis for improving the reliability and optimizing the design of the door system.
