Notes:
To reduce the cost and time of transport due to the different track gauges(narrow, standard,broad) in the Eurasian railroad network such as TKR(Trans-Korea Railway), TCR(Trans-ChinaRailway) and TSR(Trans-Siberia Railway), it is very necessary to develop and adapt thegauge-adjustable wheelsets system. The freight trains’ with gauge-adjustable system could operate onthe different track gauges in the transcontinental railway. Therefore, to assure the safety of the newlydeveloped gauge-adjustment wheelsets system, it is essential to evaluate integrity of locking parts inthe system by using fatigue analysis. In this study, it was performed that contact stress analysis oflocking parts by using FEM(Finite Element Method) in the case both the gauge changeover operationand freight trains' service in the curved track, respectively. Besides, to consider the variation of fatiguedata, the crack initiation life was statistically evaluated
