本研究将双时间尺度方法（靖川，2006；Skejic和Faltinsen， 2008）应用于船舶在风浪中漂移和振荡运动的模拟。为了获得仿真结果的验证数据，采用散货船模型在储罐中进行了自由漂移模型试验。船舱试验表明，在风浪作用下，船体漂移角大于80°，且其特性与初始航向条件无关。该方法能较准确地模拟船在风浪中的漂移行为。为了解释死船的漂移特性，对死船的运动稳定性进行了分析讨论。
In this study, the two-time scale method (Yasukawa, 2006; Skejic and Faltinsen, 2008) is applied to the simulation of drifting and oscillating motions of a deadship in wind and waves. To obtain the validation data of the simulations, free-drifting model tests are conducted in a tank using a bulk carrier model. The tank tests show that the deadship drifts with a large hull drift angle over 80° in wind and waves, and its characteristic is independent of the initial heading condition. The present method can simulate the drift behavior of the deadship in wind and waves with practical accuracy. To explain the drifting feature of the deadship, the motion stability of the deadship is analytically discussed.
