EVALUATION OF DETERIORATION IN DIESEL SHUNTING LOCOMOTIVE

초록

In order to assess the degree of deterioration, various types of technical evaluation methods for the locomotive parts were introduced. Unlike other railway vehicles in railway applications, the diesel shunting locomotive is composed of major components such as diesel engine, transmission, gear box, brake system, etc., which cover more than 70 percent of the total price of the locomotive. Therefore, in this investigation, each part of major components in the locomotive was analyzed in terms of the degree of deterioration. The performance evaluation tests were performed on the diesel engine and gear box, and precision inspection was conducted on each part of transmission to provide the current wear information. Also, corrosion tests and nondestructive evaluation techniques were employed to demonstrate the wear status of car body and bogie parts in the locomotive. In this research, several engineering characterization techniques for the performance analysis of a deteriorated shunting locomotive were applied and presented.
