摘　　要：介绍一种基于现场数据对高速动车组预防维修规程进行分析和优化的方法。通过对现场数据的收集与分析,确定适用的退化模型、寿命分布及故障发展规律;通过失效模式与影响分析确定故障模式的影响、原因及可能引发的故障后果;通过预防维修策略分析确定适当的检修策略;结合以上分析结果,确定适当的检修周期,实现对预防维修规程的分析与优化。The paper introduces an analysis and optimization method of preventive maintenance regulation for high speed EMU based on field data. Proper degradation model, lifetime distribution and the developing law of malfunction are confirmed by collecting and analyzing field data. The paper confirms the influences, reasons and potential results by analyzing failure mode as well as impact; similarly, proper maintenance strategy is determined by strategic analysis of preventive maintenance. According to the above results, overhaul period is confirmed, which realizes the analysis and optimization of preventive maintenance regulation.
