波浪附加阻力是IMO提出的EEDI公式中海洋因子的重要组成部分。目前对高速船舶波浪附加阻力的研究还比较少。本文应用2.5维理论预报了波浪中的水动力和船舶运动响应。本文在船舶运动的基础上，用几种方法预报了波浪附加阻力，并与已有的船模试验资料进行了比较。在比较的基础上，推荐了一种计算高速船舶波浪附加阻力的数值方法。
The wave added resistance is one important part of ocean factor fwin EEDI formula presented by IMO. At presently the wave added restistance research on high speed ships is relatively few. In this paper,the hydrodynamic forces and ship motion response in waves are predicted by using 2.5D theory. On the basis of ship motions, the waved added resitatnce is predicted by using several methods and compared with available model tests data. Based on comparisons, one numerical methods to predict wave added resistance on high speed ships is recommended.
