摘要:
为分析共因失效对高速铁路接触网系统的影响，将二元决策图(Binary Decision Diagram，BDD)与共因失效理论引入到接触网系统可靠性分析中。利用逻辑相邻优先组合法(Logic Neighbor Priority Connect，LNPC)将高速铁路接触网系统的故障树模型转化为BDD模型并求取其可靠度表达式，利用隐式方法对考虑了共因失效的接触网系统可靠度进行计算，利用MATLAB绘制考虑共因失效和不考虑共因失效情况下接触网系统可靠度变化曲线。研究结果表明：提出的分析方法适用于接触网系统的可靠性分析，为接触网系统的可靠性分析提供了一定的理论依据。
Abstract:
In order to analyze the influence of common cause failure (CCF) on the catenary system of high speed railway, the binary decision diagram (BDD) and CCF theory were introduced into the reliability analysis of catenary system. The logic neighbor priority connect (LNPC) method was used to transform the fault tree model of the catenary system of high speed railway into the BDD model, and the expression of its unreliability was obtained. The reliability of catenary system considering CCF was calculated by using the implicit method, and the change curves of reliability of catenary system with considering CCF and without considering CCF were drawn by using MATLAB. The results showed that the proposed method is suitable for the reliability analysis of catenary system, and it provides a certain theoretical basis for the reliability of catenary system.
