A Study on the Existing State of Preventive Maintenance and the Improvement Measures for a Point Machine

선로전환기 예방정비 현황 및 개선 방안에 관한 연구

This paper investigates the current established preventive maintenance and its corresponding data on a point machine among railway signalling facilities and suggests a part of considerable plans when the policy of the preventive maintenance is modified. It is not appropriated to apply the optimized preventive replacement period considered with the cost simply. In that case, it is suggested that the reliability should be analyzed failure mode and effects through collecting the on-site failure data sufficiently. Then, that result can be proposed to adjust the proper criteria into the rational way by comparing the initial maintenance criteria. In this paper, the alternative way to determine the feasibility of the inspection period using failure probability is introduced.
