基于FMEA和FTA的ZPW-2000A轨道电路可靠性分析
Analysis on reliability of ZPW-2000A track circuit based on FMEA and FTA
摘要
Abstract
According to the reliability issues of ZPW-2000A type jointless audio frequency-shift modulated track circuit system, the method of combining Failure Modes and Effect Analysis(FMEA)and Fault Tree Analysis(FTA)is proposed for research and analysis of the system reliability. The system is analyzed and defined, and the FMEA table is completed. All possible failure modes, failure effects, fault detection methods and remedial measures are obtained. The fault tree is built. The minimal cut sets of the fault tree are got, and the qualitative and quantitative analyses of the fault tree are conducted. The weak links of the sys-tem are located by qualitative analysis. The fail probability of roof events, important degree of each minimal cut sets and reliabil-ity index are gained through the quantitative analysis. The validity of the reliability analysis method is verified by comparison with the relevant technical requirements.关键词
