基于TS-DBN的地铁牵引系统可靠性分析
Reliability Analysis of Subway Traction System Based on TS-DBN
摘要
Abstract
In this paper,a reliability evaluation method combining continuous-time T-S dynamic fault tree and Bayesian net-work is proposed to simulate the dynamic and static failure behavior of the traction system during actual operation.Firstly,a fault tree model based on the element structure of the traction system is constructed.Then,by applying the timing rules of the T-S dynam-ic gate,the logical definition of the T-S gate is given,and then the posterior probability and importance parameters of the child nodes are calculated.The sensitive nodes are sorted to establish a mathematical model of the stability function in the continuous time state of the system.This method can intuitively reflect the sensitive and weak links of the structural units of the traction system,and can provide a theoretical reference for the optimization of subsequent maintenance strategies.关键词
