전동차 구조체의 구조해석 연구

This paper describes the result of structure analysis of body structure. The purpose of the analysis is to evaluate an safety which body structure shall be considered fully sufficient rigidity so as to satisfy proper system function under maximum load and operating condition. Material of body structure applied an aluminum alloy. Body structure consist of side frame, under frame, roof frame, end frame. FEM analysis is based on "Performance Test Standard for Electrical Multiple Unit, noticed by Ministry of Construction & Transportation, in 2000" and reference code is JIS E 7105. The analysis results have been very safety and stable for design load conditions.
