궤간 가변 압축스프링의 확률론적 피로강도 평가

초록

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, it is important to develop the gauge-adjustable wheelset system to adapt easily to these gauges. Moreover, this system accomplish a conversion operation periodically from the gauge variable segment between various gauge. Gauge variable pressure coil spring from conversion process accomplish a central role repetitively for operation mechanism between flange and locking part. Therefore, to assure the safety of the gauge-adjustment wheelset system, it is necessary to fatigue life evaluate of coil spring in the system using stress analysis. It was performed to evaluate stability of running track with UIC 510-4 code. Fatigue life of the gauge-adjustable compression spring with the variation of the fatigue strength was evaluated by fatigue life analysis simulator.
