Feasibility Check of Maintenance Period by The Operating Reliability of EMU-Focusing on the Main Components of Ansan Line EMU-

전기동차의 운행 신뢰성을 통한 유지보수주기의 타당성 검토 -안산선 전기동차의 주요부품을 중심으로-

Safety is soaring up as a core value in accordance with the recent improvement of operating speed & incidents. rolling stock is a kind of system which works together with several components. one component has an effect on the sub-system, which can cause to the train safety operation, therefore reliability management of the major components of rolling stock is a kind of solution to the safety operation of train, but realistically maintenance in korea performed based on period rather than TBO of major components, but Japan does new maintenance system based on the major components, which optimizes maintenance tasks. actually Japan can apply to new maintenance system because they are ready in planning step but in this study, making a reliability data of major components and review the adaptability of new maintenance system to the rolling stock operating in Ansan line.
