摘　　要：为了研究一阶泰勒展开边界元方法对半潜式平台的水动力性能以及运动响应的预报精度,将其计算结果与商业软件AQWA的计算结果进行比较。在试验结果的基础上,通过对两种计算方法结果的比较分析,表明一阶泰勒展开边界元方法计算结果与AQWA的计算结果吻合较好,而且一阶泰勒展开边界元方法有着较好的收敛速度,可用于半潜式平台水动力分析,本文工作也为该类平台的水动力响应分析提供了参考。In order to study the prediction accuracy of the first-order Taylor expansion boundary element method for the hydrodynamic performance and the motion response of a semi-submersible platform,the calculation results were compared with those of the commercial software AQWA.On the basis of the experimental results,through the comparative analysis of the results of the two methods,it shows that the results of the first-order Taylor expansion boundary element method are in good agreement with AQWA,in addition,the method has a good convergence speed.The method can be used for the hydrodynamic analysis of a semi-submersible platform and the work in the paper can also provide a reference for the hydrodynamic response analysis of such platform.
