以船舶操纵水动力预报为研究背景，利用商用软件Fine/Marine对DTMB5415进行了低频纯横荡及纯首摇运动数值仿真研究。以纯横荡运动幅值为0.064 m试验数据为基准，通过对比不同边界条件设置及其对计算结果的影响分析，得到随体坐标系下船模受到的侧向力及转首力矩，并将仿真计算结果与船模试验结果进行对比，获得较好的参数设置。以该设置参数及边界条件为依据进行后续的纯横荡运动及纯首摇运动数值仿真计算，得到船模所受侧向力及转首力矩。%In order to predict the shipmaneuverability in viscous flows, using commercial software Fine/Marine for DTMB5415 of low-frequency pure sway and pure yawmotion simulation, obtained the lateral force and yaw moment which fixed on the ship model.A condition test data of pure sway as a benchmark, by comparing different boundary conditions and their impact on the results, obtainthe lateral force and torque, the simulation results with the ship model test results were compared to obtain better parameter settings.In this setting the parameters and boundary conditions as a basis for subsequent pure swaying motion and pure yaw motion numerical simulation, get boats suffered a lateral force and torque under this set-ting.
