摘要： 在点吸收式波浪能发电装置中研究圆柱形单浮体的垂荡运动响应，利用水动力计算软件AQWA 对圆柱形单浮
体进行仿真分析，通过对不同吃水深度下不同直径、高度组合的单浮体进行建模仿真，得出不同吃水深度下垂荡RAOs
的变化规律。在P-M 波谱下进行时域分析，得出浮体重心位移响应曲线。在此数据的基础上在造波水池中进行实验，验
证不同吃水深度下直径300 mm、高度460 mm 单浮体垂荡RAOs 的变化规律。结果表明，在误差允许范围内，实验所得
数据与数值模拟数据相吻合，证明数值模拟结果可信，可为单浮体在发电装置中的垂荡运动响应计算提供参考。

Abstract: This paper studied the heave motion response of a cylindrical single floating body in the point absorption wave energy
generator, carried out simulation analysis on the cylindrical single floating body by using hydrodynamic calculation software
AQWA. The changing laws of drooping RAOs at different draughts were obtained through the modeling and simulation of the
single floating body with different diameters and heights under different draughts. The response curve of floating weight center
displacement was obtained by time domain analysis under P-M spectrum. On the basis of the data, experiments were carried out
in the wave-making pool to verify the changing laws of single floating body heave RAOs with a diameter of 300 mm and a height
of 460 mm at different draft depths. The results show that the experimental data are consistent with the numerical simulation data
within the allowable error range, which proves that the numerical simulation results are reliable and can provide reference for the
calculation of the heave motion response of a single floating body in a power generation device.
