1. 제 목 : “Model Order Reduction for Analysis of Mechanical Systems”
2. 연 사 : 한 정 삼 교수 (안동대학교 기계공학과)

5. 내 용 : Transient dynamic problems with large numbers of degrees of freedom in mechanical systems are nowadays solvable in a feasible computational time due to the tremendous improvement of computers. However, when the mechanical system needs to be inserted into the whole mechanical/control system model for system-level simulation or when the transient simulation of the system is included in structural optimization, the computational costs for the transient analysis still do not fit within a reasonable design process time. In order to alleviate this computational difficulty, use of the technique of model order reduction (MOR) for accurate and efficient time-dependent simulations is highly recommended.
In this talk, software mor4ansys to perform moment-matching model order reduction using a Krylov subspace via the Arnoldi algorithm directly to ANSYS finite element models will be introduced. Its successful applications to electro-thermal and structural mechanics problems will be discussed as well.
