Abstract

In this paper, the motion performance in waves for the training ship Kaya of Pukyong National University is obtained by using a computer program based on Strip method. To guarantee the pleasant seafaring in ocean, the vertical acceleration of ship motion is calculated according to the location of the ship. The results of calculation by changes of ship speed are compared with the guideline of MSI(Motion Sickness Incidence). The degree of motion sickness is shown and discussed through the comparison between calculated vertical acceleration spectrum and MSI guideline. The computational results of MSI were as follow; when ship speed increased in the order of 5 knots, 10 knots, 12 knots and encounter angle became the bow quartering sea of $120^{\circ}$ compared to $180^{\circ}$ and $150^{\circ}$, the vertical acceleration values grew higher.

본 연구에서는 실습선 가야호를 대상으로 하여 파랑 중 운동성능을 평가하였다. 그리고 쾌적한 승선감을 확보하기 위하여 실제 해상에서 운항중인 선박의 선내 위치별 수직가속도 성분을 선체운동 계산 기법을 통해서 구하고, 수직가속도 스펙트럼을 이용하여 가야호의 선속변화에 따른 가속도 계산 결과를 뱃멀미 지수(MSI; Motion Sickness Incidence)의 가이드라인과 비교 검토하여 멀미의 정도를 표시하였다. MSI 계산 결과는 선속이 5 knots, 10 knots, 12 knots로 커지는 순서대로 수직가속도의 가중치가 높게 나타나며, 입사각은 $180^{\circ}$$150^{\circ}$에 비해 선수사파인 $120^{\circ}$의 경우에 수직가속도의 가중치가 높게 나타났다.
