Calculation of Hydrodynamics and Motion Responses of Two Hinged Plates

用三维势流理论分析了两个铰接的单体在波浪的作用下所受的水动力和各自的运动响应 .所用的格林函数自动满足自由面条件和底部边界条件 ,因此只需在物体平衡位置的湿表面布置源汇 .给出了在横浪作用下两个单体的横摇和垂荡的响应曲线 .计算与试验结果的比较表明 ,所采用的计算方法是合理的 ,可以为研究波浪中两物体的相互作用作参考 .

The traditional three-dimensional potential theory was used to analyze the hydrodynamic forces and motion responses of two hinged bodies in waves. The special Green function is selected so that the sources are only distributed on the wetted surface of two bodies at the equilibrium position. The depth of water is finite. The curve of roll and heave responses of two bodies at various frequencies in beam waves were presented after calculation. It shows that the method applied in this paper is reasonable by comparison between experiment and calculation results. The method can be taken as a reference for research work on the interaction of two bodies in the water.
