도시철도차량의 보조전원장치 신뢰성 분석

Abstract

Safety management system of the railway was introduced for the maintenance of the railway vehicle. Safety management system requests for the activities of reliability management system associated with the Reliability Centered Maintenance. Thus, in order to apply the process of RCM(reliability centered maintenance), auxiliary power supply unit is selected among the 13 major units in trainset. auxiliary power supply is the significant impact item in terms of service failure and the failure rate is also the highest. So, 59 components in auxiliary power supply unit were selected and statistical analysis was performed through analysis of the field data collected during commercial operation.. The maintenance work in the future should be based on the reliability analysis results. Also, the reliability analysis may be the starting point for RCM required by the safety management system of the railway.
