도시철도차량 경량화를 위한 하이브리드형 차체 모델 연구

초록

In this paper, We made a simple Box type model and suggested a material substitution solution for weight reduction. For making a simple Box type model, average thickness of standard EMU are considered. We compared the simulation results of a standard EMU and a simple BOX type model under the static load test, and obtained good correlations from both results. To make a hybrid bodyshell, we use a variety of materials and compared their results. It is considered that the developed approach to predict weight reduction rates of hybrid bodyshells in case that the materials of underframe structures are substituted.
