摘要/Abstract

摘要： 根据接触网的可修特性,采用马尔可夫(Markov)理论和数理统计的原理,建立了接触网可靠性分析的数学模型,推导出了接触网系统的稳态有效度、可靠度和平均故障间隔时间等重要特征量的计算公式.用此模型对宝成线的可靠性进行了预测和分析,在同国外接触网系统的可靠性进行比较的基础上,提出了提高我国接触网系统可利用度的有效措施.为铁路系统的可靠性设计、维护和科学管理提供了理论依据和新的方法.

关键词: 接触网系统, 有效度, 可靠性分析, 马尔可夫理论

Abstract: Reliability of the railway catenary system is a key to the safety of trains.In this paper, a mathematical model is established using the Markov theory and statistics based on the repairable characteristics of catenary.Availability, reliability and the mean failure time are derived.Reliability of the Bao-Cheng Railroad is analyzed and forecasted with the model.It is compared with the reliability of overseas catenary.Effective measures are proposed to improve catenary reliability.This study provides a theoretical basis and a new method for reliability design, maintenance and management of the railway system.

Key words: Markov theory, availability, catenary system, reliability analysis
