以动力定位船为研究对象，通过船型变换生成供应船的系列船型。基于CFD数值模拟约束模平面运动机构（PMM）试验中的斜拖试验，得到系列船型在不同漂角时所受的横向力和转艏力矩，经最小二乘法拟合求得各船型的位置水动力导数。在此基础上，通过多元回归，得到位置水动力导数关于船型参数的回归公式，以为设计阶段动力定位船位置水动力导数的确定提供简便的方法。

This paper takes the dynamic positioning supply vessel as the research subject, and a series of ship models are generated through hull form transformation. The CFD method is applied to numerically sim-ulate the drift Planar Motion Mechanism(PMM)test to calculate the hydrodynamic characteristics of the models in different drift angles. Then, the location hydrodynamic derivatives are obtained with the least squares fitting method. On this basis,the regression formula of location hydrodynamic derivatives is ob-tained through multiple regression, which provides an easy method to determine hydrodynamic derivatives during the preliminary design stage.
