Reliability Evaluation of Pantograph System Based on Fault Tree-Bayesian Network
摘要
Abstract
Pantograph is an important electrical equipment for urban rail transit vehicles,whose stability directly affects the stability of the traffic flow.The good performance of the pantograph is one of the guarantees of the safe operation of the vehicles.In order to solve the limitation of the fault tree analysis method of the reliability evaluation of the pantograph system,the fault tree analysis method and Bayesian network are combined to study the reliability of the pantograph system.This method not only can calculate the reliability index of the pantograph system,but also can solve the failure probability of each component when the system fails,and then the reliability degree of the various components of the system is obtained.The positive and negative reasoning diagnosis is carried out to identify the weak link,the efficiency of its reliability analysis is improved,which provides a theoretical basis for the reliability evaluation and fault diagnosis of the pantograph system of metro vehicles.关键词
