为准确估算滑行艇的水动力性能，基于RANSE VOF 求解器，选取滑行艇拖曳阻力模型实验和耐波性模型实验，采用切割体网格和整体动网格技术，对滑行艇在静水中的高速直航和在规则波浪中的迎浪运动进行了多自由度数值模拟．为验证模拟的真实性，将模拟计算值与实验值进行比较，结果表明，计算流体动力学技术可以准确且高效地模拟滑行艇在静水以及波浪中高速航行时的运动姿态和水动力特性，为滑行艇设计提供可靠的参考依据．

In order to accurately estimate the hydrodynamic characteristics of planing crafts,the high-speed sailing ofplaning crafts in calm water and in regular head waves was numerically simulated with multiple degrees of freedom byperforming resistance model experiments and seakeeping model experiments.In the simulation,the RANSE VOF solverwas adopted and the trimming mesh technique as well as the integral dynamic mesh method was employed.Theresults were then compared with the experimental data to verify the accuracy of the simulation.It is found that theadopted computational fluid dynamics technique helps to accurately and efficiently simulate the sailing attitude andhydrodynamic characteristics of high-speed planing crafts in calm water and in waves,and that the simulation providesa credible reference for the design of planing crafts.
