300m 장대레일 적재 화차의 기존선구간 적정 주행속도 결정에 관한 연구

In this study is presented a numerical method which assesses running safety of the freight car loading with 300m CWR and structural safety of conventional railway track and fastening when passing over sharp curves and steel girder bridges. Optimal speed of the freight car is suggested based on the numerical reviews of the safety against derailment of the freight car and structural safety of track and fastening at vulnerable points of the conventional line.
