고속 컨테이너 화차 차체의 구조강도 평가

Recently, it has been trending toward speed-up not only in the passenger car but in the freight car. In this study, we thus performed stress analysis for the carbody for high speed container freight car in use and field test of the freight car in Gyungbu-Iine so that we may utilize the results as a design guide for speed-up hereafter. Five vertical loading conditions due to dynamic effect and the weight of the carbody and the container applied to locking devices of the carbody and its results are compared with that of a test. As a result, we found that there is need to complement the strength of the carbody in some measure when speed up the present freight car.
