대형 구조물의 Krylov 부공간 모델차수축소기법 기반 효율적인 주파수응답 및 응력 평가

권기범, 한정삼(안동대학교)
In this paper, the frequency response analysis of a base frame supporting a large centrifugal compressor and a model order reduction technique operated on ANSYS are introduced. First, the frequency response and the stress evaluation of the base frame are performed using the full-order FE models. Then, the Krylov subspace based model order reduction technique, which improves the efficiency of the analysis and maintains the numerical accuracy, is applied for the frequency response and the stress evaluation.
