【摘要】：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。
[Abstract]:Based on the prediction of ship maneuvering hydrodynamics, the numerical simulation of low frequency pure roll and pure first roll motion of DTMB5415 was carried out by using commercial software Fine/Marine. Based on the test data of pure swinging motion of 0.064 m, by comparing the different boundary conditions and their effects on the calculation results, the lateral force and the turning moment of the ship model in the coordinate system are obtained. The simulation results are compared with the results of ship model test, and better parameter setting is obtained. According to the setting parameters and boundary conditions, the numerical simulation of pure swinging motion and pure first roll motion is carried out, and the lateral force and turning moment of the ship model are obtained.
