Abstract

Recently, as aviation industry has been activated, development of software related to composite materials has been demanded. Composite analysis requires specialized structural analysis and test evaluation. Therefore, it is necessary to use existing commercial software to analyze the composite structure, but existing commercial software only provides limited functions. Especially, since there is no specialized software for corner structure analysis of aerospace composites spa structure, much human resources and time are consumed in structural analysis. In order to solve this problem, we developed a GUI-based automation software based on user-friendly GUI that reflects the existing corner structure analysis procedure and provides multiple breakdown criteria. To verify the reliability of the structural analysis results of the developed software, it was confirmed that there is no problem in the structural analysis performance as a result of comparing with the existing analysis results.

최근 항공 산업이 활성화됨에 따라 복합재 관련 해석 소프트웨어의 개발이 요구되고 있다. 복합재 해석은 전문적인 구조 해석 및 시험 평가가 필요하다. 따라서 복합재 구조 해석을 위해서는 기존의 상용 소프트웨어를 사용할 수밖에 없으나 기존의 상용 소프트웨어들은 제한적인 기능만을 제공하고 있다. 특히 항공기 복합재 스파 구조물의 코너 부 구조 해석에 특화된 소프트웨어는 전무하기 때문에 구조 해석에 많은 인적 자원과 시간이 소비되고 있다. 이를 해소하기 위해서 기존의 코너 부 구조 해석 절차를 반영하고 복수의 파손 기준을 제공하는 사용자 친화적인 GUI 기반의 자동화 소프트웨어를 개발하였다. 개발한 소프트웨어의 구조 해석 결과에 대한 신뢰성을 검증하기 위해 기존의 구조 해석 결과와 비교한 결과, 구조 해석 성능에 문제가 없음을 확인하였다.
