摘　　要：滑行艇在滑行状态的航行往往伴随着浸湿面积及纵倾角的变化,导致其快速性性能难以评估。为此,本文基于全结构化动态重叠网格求解运动姿态,引入六自由度模块,采用Level-Set水平集方法求解自由液面,对某型槽道滑行艇进行快速性数值仿真。最终,得到了滑行艇在各个航速下对应的阻力、纵倾角、自由液面波形、中纵剖面气液分布以及船底压力分布。为验证可靠性,将纵倾角仿真结果与实船试验结果对比,结果吻合较好。It is difficult to evaluate the resistance performance of planning craft due to the variation of wet area and pitch angle.In this paper,structured dynamic overlap grid technique is used to calculate ship motions and Level-Set method are employed to simulate the free surface.Finally,the resistance,pitch angle,free surface waveform,gas-liquid distribution in the middle longitudinal section and bottom pressure distribution of the planning craft at different speeds are obtained.The calculation results of pitch angle show an agreement with full-scale test result.
