| 摘 要： | 基于B样条理论的特点,提出一种高效的船体水动力网格划分方法,开发相应的程序。将此方法直接应用于某50万t矿砂船的三维线性频域水动力计算中,将计算结果与文献结果进行对比分析,其结果与相关文献结果非常吻合,认为用B样条方法进行船体水动力网格划分是可行。

| Abstract: | A convenient and precise method to mesh the 3D hydrodynamic grid of ship was proposed and programmed based on the B-spline method.The method was applied in the 3D hydrodynamic computation for a 500 000 DWT ore carrier,and the numerical results were in good accordance with that of published paper.So it is feasible to apply the B-spline method in meshing the wet surface for the hydrodynamic calculation of ship. |
