摘　　要：浮子是振荡波能发电装置的关键部分之一,影响着能级的转化效率。利用ANSYS有限元软件Hydrodynamic Diffraction模块建立了圆柱型浮子和圆锥型浮子的有限元模型,通过改变其吃水深度,分析Z方向上的激励力,判断其较优尺寸;利用两者优化后模型构建陀螺型浮子有限元模型,并进行水动力分析。研究利用ANSYS有限元软件Hydrodynamic Diffraction模块验证了陀螺型浮子的优越性,证实了此模块在水动力分析中的可靠性和为实现振荡波能发电装置的小型化密集化提供了理论依据。The float is the key part of the oscillation wave energy power generation device and it influences the transfer effi- ciency of energy level. By the Hydrodynamic Diffraction model of the ANSYS software, this paper builds the finite element model on the cylindrical float and the cone float, and gets the Diffraction and Froude-krylov force on the z direction to deter- mine the better size of common float ; then builds the gyro float and does hydrodynamic analysis. This paper uses the Hydrody- namic Diffraction module of the ANSYS software to verify the superiority of the gyro float, and to confirm the reliability of the module in analysis of the Hydrodynamic, it provides a theoretical basis for the miniaturization of oscillation wave energy power generation device.
