Abstract

This paper describes a seismic analysis of chemical pump using automated mesh generation system. The use of an automated analysis system, involving FE codes together with CAD systems and FE pre- and post-processors, has provided an important step towards shortening the design process and structural optimization. The FE model, which is a FE mesh accompanied with the analysis condition, is automatically converted from the analysis model. The FE models are then automatically analyzed using the FE analysis code. This integrated FE simulation system is applied to an analysis of three-dimensional complex solid structures such as a chemical pump.

본 논문은 자동요소생성 시스템을 이용한 화학적펌프의 지진해석에 대한 내용이다. 전처리시스템을 CAD시스템, 유한요소 코드와 통합시킨 자동화된 해석시스템은 구조물 최적화 디자인에 효과적으로 사용되어 진다. 해석조건이 수반된 유한요소모델은 자동적으로 해석모델로 부터 생성되어 진다. 또한, 유한요소모델은 해석코드에 의해 자동적으로 해석되어 진다. 이 통합화된 유한요소 시뮬레이션 시스템의 효용성을 화학펌프와 같은 3차원 복잡구조물에 적용하여 보았다.
