고속철도차량 견인전동기의 완전 분해정비 최적 주기

Concerning the total life cycle cost of rail vehicle, operation/maintenance cost accounts for approximately 70%, among which have a higher percentage. Maintenance costs for maintaining the availability of the normal operation of the system. For a complete overhaul cycle of the high-speed railway vehicle traction motors, it is selected without considering the criticality with respect to the lower component being implemented. In this paper, The Failure data of traction motor about high-speed rail vehicle is analyzed to evaluate probabilistic properties and reliability of the criticality of the lower component. Also in terms of reliability centered maintenance , Optimization of the complete overhaul period is performed.
