道岔和道岔是铁路网的重要组成部分。任何S&C故障通常会导致列车延误和取消，对所提供的服务质量、铁路安全和运营成本产生负面影响。S&C是一个多组件系统，为了能够主动预防S&C单元故障及其不良后果，需要在组件级别预测问题的能力。本文介绍了在现场数据的基础上推导出各个自动控制部件的寿命分布。维护被认为是导致报告的S&C故障频率增加的潜在因素。分析结果和开关单元元件的寿命分布提供了一种预测维护活动的预期数量的方法，以及在任何指定时期内这些单元的相关成本。它们为开发资产管理策略的维护优化提供了必要的输入。
Switches and crossings (S&C) are critical elements on railway networks. Any failure of S&C usually leads to train delays and cancelations having a negative impact on the quality of service delivered, railway safety and also operating costs. S&C is a multi-component system and to enable proactive prevention of S&C unit faults, with their undesirable consequences, the ability to predict problems at component level is needed. This paper describes the derivation of lifetime distributions of individual S&C components based on field data collected. Maintenance was identified as a potential contributor towards increased frequency of reported S&C faults. The outcomes of the analysis and lifetime distributions for the elements of the switch units provide a means of predicting the expected number of maintenance activities, and associated costs for these units over any specified period of time. They provide an essential input to the optimisation of maintenance in developing an asset management strategy.
