Abstract

This article deals with a case study on determining the replacement interval for the extraction motor in KTX. The reliability is analysed with the field data from 42 months. The effect of the replacement interval on service reliability, availability, safety and lifecycle cost are evaluated through simulation which is done by the commercial tool, Availability Workbench AvSim Module. As the results of the analyses, a new replacement interval is presented to reduce the lifecycle cost while service reliability, safety and availability are satisfactory.
