摘　　要：基于三维势流理论的水动力商业软件AQWA用于多种浮式结构物在波浪上运动的分析。而在国内鲜见以AQWA为平台计算船舶的运动响应,因此本文以方形系数为0.7的系列60船为例,研究AQWA是否可以用于预报船舶耐波性能,并将AQWA的计算结果与基于STF法的Seakeeper的计算结果和水池试验结果进行对比。通过对比发现,利用AQWA计算得到的船体运动响应合理地反映了系列60船的实际耐波性能,可用于船舶波浪载荷预报。The AQWA,a commercial hydrodynamic software,which was based on 3-D potential flow theory. It is used to analyse a wide range of floating structures moving in the waves. In domestic,however,it is rare to see people calculating the motion response of ship by AQWA,therefore,this paper aims to discuss whether AQWA can be used to predict the seakee time, compared the calculating results by AQWA ping performance of series 60 （c~ = 0.7）. At the same with those by Seakeeper which was based on STF and those by experiment. As a result, it indicates that the data of the AQWA reasonablly reflected the seakeeping performance of series prediction motion response which was calculated by 60, so that it can be applied to wave load
