마리나 항만 내 부유식 구조물의 상하 운동 저감을 위한 몰수체 수치 해석 연구

초록

A numerical study on the hydrodynamic analysis of a barge-type structure connected to a submerged body is conducted. Two-degree-of-freedom system is modeled to simulate the vertical motions of both the barge-type buoy and the submerged body. The optimum frequencies are observed to minimize the Heave RAO of the barge-type floating buoy. The frequencies vary according to the submerged body and the connection between two bodies. The parametric study is conducted for various projected areas of the submerged body and the spring stiffness of the connection.
