마그네슘 합금을 이용한 표준전동차 도어의 경량화 연구

Recently environmental regulations are getting strengthened. Due to this regulation trends, reducing pollution and energy consumption technologies are being actively developed. One of the techniques for reducing energy consumption is lightweight technology, it can reduce energy consumption and studied in various fields. Lightweight technologies also can important things to achieve high speed rail. So in this paper, to contribute to reduced emissions and weight reduction of train, make a target to train doors for 2 percent of the total weight of train and door are reduced by change material. And computational simulation will be implemented and evaluated whether the conditions are satisfied.
