Fatigue Analysis of Locking Parts in the Gauge-Adjustable Wheelset System Considering the Variation of the Fatigue Strength

초록

To reduce the cost and time of transport in the Eurasian railroad network 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 wheel set system to adapt easily to these gauges. Therefore, to assure the safety of the gauge-adjustment wheel set system, it is necessary to evaluatee integrity of locking parts in the system using fatigue analysis. In this study, it was performed to contact stress analysis of locking parts by using FEA (finite element analysis) simulator during the gauge changeover operation and freight trains' service in the curved track, respectively. Based on these results, the fatigue life of locking parts with the variation of the fatigue strength was evlausted by a durability analysis simulator.
