궤도재료의 피로ㆍ열화손상개소 탐상 및 분석기법 체계화

It is estimated that the running of locally-developed next generation High Speed Trains with maximum speed of 400㎞/h will help to deteriorate track components. It was presented that the rail defect coding system in UIC 712R includes the definitions of damage types of rail, maintenance procedures, and etc to detect and maintain. It is necessary to make a track maintenance manual determining maintenance periods using the standardization of damage types of track components such as: sleeper, fastener, elastic pad. In this study, the damage types of high speed track components are investigated by referring domestic and foreign literatures. And then the damage types of rail given in UIC 712R is reclassified more particularly and classified damage types of track components using internal high speed railway. In conclusion, this study suggests that track maintenance will be efficiency through the standardization of the scientific detect and analysis technique according to the damage types of track components on internal high speed railway.
