단순 Box형 차체의 경량화를 위한 이론적 개념설계 모델 연구

초록

In this paper, a theoretical approach is studied to derive a simple box-type model for weight reduction design. For deriving a simple box-type model, axial, vertical and twisting deformations are considered under constant stiffness and strength conditions. We compared the theoretical results with the simulations of a simple box-type model under the static load test conditions for urban transits, and we obtained good correlations between both results. It is evaluated that the developed theoretical simple box-type model can be used for the weight reduction design of urban transits.
