To reduce the cost and the time of transport in Eurasian railroad networks such as TKR(Trans-Korea Railway), TCR(Trans-China Railway) and TSR(Trans-Siberia Railway) 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. Moreover, this system accomplishes periodically a conversion operation from the gauge variable segment between different gauge. Gauge adjustable compression coil spring during conversion process accomplishes repetitively a central role for operation mechanism between flange and locking part. Therefore, to assure the safety of the gauge-adjustment wheelset system, it is necessary to stress analysis of the optimized spring in the system. In this study, it was performed to optimal design of the spring for stress analysis by using the genetic algorithm and to stress analysis of the optimized spring by using FEA(finite element analysis)

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 510-4code. Fatigue life of the gauge - adjustable compression spring with the variation of the fatigue strength was evaluated by fatigue life analysis simulator
