摘要
分别用传统故障频次分析和故障比重比分析两种分析方法,对所采集的CRH2型动车组制动系统故障数据进行了统计分析,找出了影响动车组制动系统可靠性的薄弱环节,为提高动车组制动系统的可靠性提供了研究方向。
Two analytical methods of traditional failure frequency and the failure density proportion are respectively applied in the statistical analysis of the failure data,which were collected from type CRH2 EMU break systems in the scene. The weakness that influences the reliability of EMU break system is presented,which provides the research direction for improving the reliability of EMU break system.
