Abstract

This paper introduces the development of temperature mapping code between thermal mesh and structural mesh in KARI Satellite Design Software. Generally, temperature distribution of a satellite varies with the time by the space environment of the orbit, so thermal expansion of the structure should be analysed in design of the satellite. For the sake of the coupled thermal structural analysis, an interpolation algorithm between two finite element heterogeneous grids has been proposed by which temperature transfer is successively conducted.

본 논문은 한국항공우주연구원에서 개발 중인 위성종합설계 소프트웨어의 부분들 중 열 해석 및 구조해석 격자 사이의 온도 해석 결과를 변환하는 알고리즘에 대한 전반적인 연구 내용을 기술한다. 일반적으로 인공위성은 궤도상의 다양한 우주환경에 따라서 온도가 시간에 따라 변하며 이에 따른 열변형을 고려한 구조적 안정성을 설계 단계에서 고려해야 한다. 본문에는 유한요소 열-구조 연계해석을 위한 이종 격자 간 온도 정보를 보간하는 방법을 제시하였으며 이 방법을 통해 온도 변환이 잘 수행됨을 확인할 수 있다.
