摘　　要：文章探讨了舰船在三维非规则波中,基于方向谱的六自由度摇荡及动力响应统计特征值的计算方法,并给出了计算结果和实船海试结果的对比,证实了算法是可行的,精度高于舰船在二维非规则波中基于频谱的计算结果。在此基础上,提出了舰船在三维非规则波中航向航速优选的求解模式和算例。A method of calculating the statistical characteristics of six degrees freedom oscillation and dynamic response of the ship in three dimensional irregular wave based on the directional spectrum is discussed in this paper. Good agreement is obtained by comparing the results of numerical simulation with data from the test at sea, and the accuracy is better than two dimensional. The algorithm and example of course and speed optimization of the ship in three dimensional irregular wave is derived later.
