基于STAR-CCM+软件平台，采用RANS方程和VOF算法，针对某一具体船模进行PMM运动数值模拟，考虑自由液面的兴波与航行过程中船模姿态的变化。建立船模按斜航运动、纯横荡运动以及不同振荡模式下首摇运动3种工况下的操纵性水动力导数求解方法。并将仿真计算结果与采用回归方程求得的结果进行比较，证明基于STAR-CCM+软件平台该方法求解水动力导数的有效性。
On STAR-CCM+ software platform, the article uses the RANS equations and VOF method, a numerical simulation on PMM movement for a specific model, considering the free liquid surface and the attitude of the model change in the process of oblique towing, maneuverability hydrodynamic derivative solving method is established with three conditions, including drifting motions, swaying motions and yawing motions of different oscillation modes, the results of simulation calculation was compared with the results by regression equation,confirmed the effectiveness of the method to solve the hydrodynamic derivatives based on the software platform of STAR-CCM+.
