Deterioration Analysis of a Shunting Locomotive: Carbody and Bogies

입환기관차의 노후도 평가 : 차체 및 대차

Deterioration analysis was performed on carbody and bogies of a shunting locomotive, which has been used for shunting works in steel making processes. In this investigation, various types of technical evaluation methods for the locomotive were employed to assess the current deterioration status. Corrosion test and nondestructive evaluation (NDE) techniques were employed to demonstrate the wear status of the carbody and bogie parts in the locomotive. Since the locomotive has been working under corrosive environment, the corrosion tests with x-ray analysis for exterior part of the locomotive were conducted to examine the evolution of corrosion reaction, and NDE techniques such as ultrasonic testing, magnetic particle testing, and x-ray radiography, were conducted on the carbody and bogies to inspect any possible inherent and/or in-service flaws. In this paper, the degree of deterioration in a shunting locomotive has been presented based on the analysis results.
