궤간가변화차의 주행안전성 수치해석 연구

Gauge-changeable vehicles can be used to connect the trans-Korean railway with the trans-Siberian railway having a different gauge for the fast and safe transportation instead of transshipment or bogie-changing. In this paper, the dynamic characteristics of a gauge-changeable freight wagon was analyzed numerically in terms of rolling stock approval from the point of view of safety, track fatigue and running behaviour. The assessment quantities for the approval were calculated using ADAMS/Rail in each case of railways in South Korea, North Korea and Russia, which showed that most quantities are less than the limit values.
