Abstract

There are two kinds of methods in the analysis of ship motion in irregular waves. The one is the spectral method in which the ship motion is assessed with spectral of irregular waves times R.A.O. of a ship. The other is, so called, time domain analysis, in which the irregular waves are used directly in the equation of ship motion to calculate the responses. In this paper, both methods are applied for the calculation of course keeping motion of a ship in irregular waves with auto-pilot control. And, the differences and useful1ness of the two methods in the assessment of auto-pilot system are compared.

불규칙파중의 선박의 운동을 해석하는 방법으로 주파수 영역해석법과 시영역해석법이 있다. 주파수영역해석법은 스펙트럴해석기법에 의해 불규칙파중 선박의 운동특성을 구하는 방법이고, 시영역해석법은 불규칙파를 생성하여 이 파를 실제의 입력으로 하여 선박의 운동을 직접 계산하는 방법이다. 보통 취급이 간편한 주파수 영역해석법이 선박의 자동조타 시스템 평가에 자주 사용되고 있으나, 본 연구에서는 주파수 영역해석법과 시영역해석법에 의한 불규칙파중의 선박의 보침운동 및 자동조타 시스템 평가를 수행하고 두 방법을 비교 검토하였다.
