【摘要】 利用Rankine源方法对浮体进行水弹性响应分析时,尤其对超大型集装箱船而言,主要关注船体网格对响应结果的影响,但通过计算发现自由面网格划分会对时域模拟结果产生较大影响,本研究通过对某超大型集装箱船23kn航速顶浪航行下自由面收敛性探究,研究了自由面尺度和网格尺寸对船体运动和水弹性载荷的具体影响,总结分析规律并提出针对自由面网格及相关建模参数选择的建议。更多还原

【Abstract】 When the Rankine source method is used to analyze the hydroelastic response of a floating body,especially for ultra-large container ships,the influence of the hull grid on the response results is the main concern.However,it is found that the free surface meshing will have great impact on results in the time domain.In this paper,it is found that the scale of the free surface and grid size have specific effects on motion and hydroelastic load by the research of the convergence of the free surface of an ultra-large container ship at 23 kn in head sea.characteristics is analyzed and suggestions for the selection of free surface mesh parameters are put forward.更多还原
