Abstract
In these days, the world have been increasing navy forces such as aircraft carriers and high-tech destroyers etc. and the importance of submarines is being emphasized. Therefore, accurate values of the derivatives in equations of motion are required to control motion of the submarines. Hydrodynamic coefficients were measured by the vertical planar motion mechanism(VPMM) model test. VPMM equipment gave pure heave and pitch motion respectively to the submarine model and the forces and moments were acquired by load cells. As a result, the hydrodynamic coefficients of the submarine are provided through the fourier analysis of the forces and moments in this paper.
최근 들어 전 세계적으로 항공모함과 첨단 구축함 등 대규모의 최신 함정위주의 해상전력을 강화하는 상황에서 잠수함의 중요성이 더욱 부각되고 있다. 이에 따른 잠수함의 운동조종을 위한 정밀한 동유체력 미계수 값이 운동방정식에서 요구된다. 수직면 평면운동시험(VPMM)장비를 이용한 동유체력을 측정하였다. 심도를 변화하면서 잠수함 모형에 상하요, 종요 운동을 각각 주었고, 이를 로드셀을 이용하여 힘과 모멘트를 각각 획득 하였다. 그 결과, 푸리에 해석을 통한 수중잠수함 모형의 동유체력 계수를 얻었다.
