| 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.

| 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. |
