CHARACTERIZATION OF DETERIORATION IN A SHUNTING LOCOMOTIVE FOR LIFETIME ASSESSMENT

초록

The deterioration of a shunting locomotive was characterized for the lifetime assessment. The locomotive was using for shunting works in steel industry, and in this paper, various types of technical evaluation methods for the locomotive parts were introduced. Unlike other rolling stocks 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 diesel 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 test and nondestructive evaluation techniques were employed to demonstrate the wear status of coachwork and bogie parts in locomotive. In this investigation, several engineering characterization techniques for the lifetime analysis of a shunting locomotive were applied and presented.
