In order to solve the problem of traffic holdups and environmental pollution(contamination), several metropolises are operating the subway and many local government plans hereafter the light rail vehicle operation and it is in the process of preparing. This point of time, it need to evaluate the comfortable characteristic of the seat which is closely connected with passenger and it should be reflected to the product design through the data analysis. The methods of the comfortable characteristic evaluation should be considered to various methods from physical factor to psychological factor. Among these, the most universal and possible quantitative measurement estimate through "Body pressure measurement system". From this paper, it was measured the body pressure of the subway seat which is in the process of operating in a domestic and it will be compared and analyzed the material & seat shape, so we evaluated the comfortable characteristic of the short-distance transportation railway vehicle. It was operated the man and woman who belongs in standard shape of Korean, we compared and analyzed the Peak position where the body pressure is visible and body pressure spread out.

자기부상열차의 부품은 그 특성상 경량화가 필수적이다. 본 연구는 자기부상 열차의 시트를 경량화하는 경향시트를 설계하기위해 CAE를 적용하여 최적의 시트를 개발하는 방법론을 알아보았다. 유한요소 해석으로 열차 시트 프레임이 설계기준에 적용된 JIS E 7104를 만족하는지 판단하였다. Topology Optimization으로 최소한의 형상으로 힘의 분포를 견디는 구조물을 선정하였다. 이 최적화한 형상을 시트의 구조 설계에 적용하였다. In this study for Light Weight Seat of Maglev, the methodology was found to develop optimized seat using CAE. The seat frame must satisfy JIS E 7104 which was applied to judge the structural strengths. Then the seat frame was changed to the minimal shape to bear force distribution using Topology Optimization. This optimized frame was applied to the design of Maglev's seat structure.
