Abstract

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 called "AUTO-RAP" and could perform simultaneously structural design and verification for railway carbody structures made of aluminum extrusion independent of expertise and experience of design engineers. Design engineers are able to conduct the knowledge-based design by providing database of existing aluminum extrusion or user-defined function. The design verification is automatically programmed to evaluate its structural integrity according to Korean Railway Safety Law or Urban Transit Safety Law. In addition, this program could automatically generate an executable file of various commercial finite element programs such as ANSYS and ABAQUS 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 design cost and time of carbody structures aluminum extrusions in railway industry.

본 연구의 목적은 설계자 전용 알루미늄 압출재 철도차량 차체 구조물의 자동화 구조해석 지원프로그램을 개발하는 것이다. 본 연구에서 개발된 프로그램 명칭은 "AUTO-RAP"이며, 알루미늄 압출재 철도차량 설계 및 구조해석에 대해 전문적인 지식과 경험이 없는 엔지니어도 설계와 검증이 동시에 가능하도록 하였다. 설계자는 기존의 알루미늄 압출재의 데이터베이스를 활용하거나 사용자 정의에 의한 지식기반설계가 가능하도록 하였으며, 설계검증은 철도안전법과 도시철도차량 안전기준에 관한 규칙에 의거하여 철도차량 차체 구조 안전성을 자동으로 평가하도록 프로그래밍 하였다. 또한, 본 프로그램은 MFC(Microsoft Foundation Classes)를 사용하여 GUI 환경을 구축하였으며, ANSYS와 ABAQUS 같은 다양한 상용 유한요소해석 프로그램 및 CAD 프로그램과의 호환성을 위해 .stp, .iges 등의 파일 생성을 지원한다. 결론적으로, 본 프로그램을 통하여 알루미늄 압출재 철도차량 차체 구조물의 제품 설계 비용과 시간 단축에 기여할 것으로 판단된다.
