UIC 기준에 따른 궤간 가변 윤축의 내구성 평가

Durability Evaluation of the Gage - Adjustable Wheelset System According to UIC Standard

To reduce the cost and the time of transport in Eurasian railroad networks such as TKR, TCR and TSR owing to the problem of different track gauges (narrow/standard/broad gauge), it is important to develop the gauge - adjustable wheelset system to adapt easily to these gauges. The gauge - adjustable wheelset system in the transcontinental railway have been proposed as a more effective way in comparison with other techniques for overcoming difference in track gauges. Assume that the freight train with gauge adjustable wheelset system is running from domestic train network to TCR, TSR in Eurasian continent, it is necessary to estimate the safety of this system. This study is evaluated at examination of safety for freight train with gauge adjustable wheelset system by simulated durability analysis. Moreover, the predicted fatigue life at running track using the durability simulator was verified by the durability test according to UIC standard.
