摘　　要：针对以周期修为主的维修模式存在效率低下、灵活性差、作业时间长等问题,将接触网系统状态作为考察变量,对维修计划进行优化。建立高速铁路接触网状态评价体系,构建接触网状态退化模型,结合谱分析结果刻画接触网系统状态退化过程,进而实现接触网系统状态维修。经实际线路分析验证,所述模型能准确描述接触网状态退化趋势,在保障接触网系统安全性的同时可有效降低维修成本,提高接触网维修管理水平。With regard to the problems of low efficiency,poor flexibility and long operation time in the maintenance mode dominated by periodic maintenance,the OCS status is taken as the inspection variable to optimize the maintenance plan.The OCS state evaluation system of high-speed railway is established,the OCS state degradation model is established,and the OCS state degradation process is depicted based on the spectral analysis results,so as to realize the OCS state maintenance.The actual line analysis shows that the model can accurately describe the degradation trend of the OCS state,effectively reduce the maintenance cost and improve the OCS maintenance management level while the OCS safety is being ensured.
