摘　　要：从受力分析的角度 ,建立了垂荡和纵摇的数学模型。给出了模型中各个参数的计算方法 ,尤其是对水翼产生的升力进行了详细地分析。为了验证模型的有效性 ,基于一艘高速水翼双体船HC2 0 0B ,使用Matlab的Simulink工具箱进行了仿真研究 ,给出了在 12个航速点的上浮量和纵倾值 ,以及在设计航速的船体姿态。对比仿真数据和实验数据 ,包括高速域附近的数据 ,二者相符得很好 。From the angle of analyzing the forces acting on the ship, the mathematical model is established of heaving motion and pitching motion in still water. The calculations of every parameter in the model are presented, and especially the lift forces of hydrofoils are detailed. For the purpose of validating the effectiveness of the mathematical model, based on a hydrofoil catamaran, HC200B, the simulation research is carried out, by use of Mablab's Simulink toolbox, so that the elevations and trim angles are obtained corresponding to 12 velocity points and the variation of the boat's attitude at the design speed is also obtained. In comparison with the simulation results and experimental data, it is shown that both of them agree well with each other, especially in the vicinity of high speed, which exhibits the effectiveness of the proposed mathematical model.
