Development of Automated Structural Design and Analysis Aided-Program of Aluminum Extrusion Carbody Structures for Railway Vehicle

알루미늄 압출재 철도차량 차체 구조물의 자동화 구조 설계 및 해석 지원 프로그램 개발

The purpose of this study is to develop automated structural design and analysis aided-program of aluminum extrusion carbody structures for railway vehicle. This developed program is possible to perform simultaneously structural design and design verification of aluminum extrusion profiles independent of expertise and experience of design engineers. Design engineers was able to design it using database of existing aluminum extrusion profiles or user-defined function. The design verification was programmed to evaluate its structural integrity according to Korean Railway Safety Law or Urban Transit Safety Law. Also, this program could automatically generate an executable file of various commercial finite element program and CAD files such as stp and iges by GUI environment applications using MFC(Microsoft Foundation Classes). In conclusion, it is expected to contribute to reduce product development time and improve product quality of aluminum extrusion profile and structures in railway industry.
