자유표면탱크의 연성운동에 관한 실험적 연구

초록

This study is on the free surface tank. The purpose is to observe coupled motion(roll-heave-sway) effect related to true roll motion experimentally. For this study, Bench Tester which could cause coupled motion was designed and developed by using hydraulic control system. To verify the reliability about experiment by develped Bench Tester, I carried out the experiment with the same condition of Vugts's experiment. Then, the results coincided with those of Vugts very well. After investigation on moment and phase of true roll motion and coupled motion, I checked out that there were considerable difference between two tanks.
