摘要
分析国内轨道系统可靠性预测和维修策略研究现状,对国内基于轨枕状态的铁路轨道系统可靠性失效判断准则进行改进研究,进而应用马尔可夫链法进行可靠性预测研究,并以此为基础通过引入轨枕维修重要度的概念进行维修策略制定方法研究。其研究成果能有效改善目前国内轨道系统维修中存在的不足,在保证轨道系统可靠性的前提下降低运营成本。
This paper analyses the current research status of reliability prediction and maintenance policy for rail track system.The failure rule of railway is improved and the forecasting method of railway reliability is given.Finally,in terms of the research of reliability the new maintenance decision method is proposed.The research can save operating costs and meet the need of railway reliability.
