摘　　要：提出一种振荡水柱式锥形中心管波浪能供电浮标。首先,介绍浮标的结构及工作原理,其次,设计3种模型方案。建立浮标在入射波下受迫运动的数学模型,进行数值模拟计算,获得浮标在设计工况下的附加质量、阻尼系数、波浪激励力、运动响应等水动力学参数。最后,通过物理模型试验,获得各设计方案在不同周期下的俘获宽度比,并与数值计算获得的俘获宽度比进行对比分析。结果显示:不同设计方案的浮标适应不同的水深条件,设计方案中模型1的俘获宽度比最大数值为47.8%。A wave powered buoy with oscillating water column and conical central tube was presented in this paper.Firstly,the structure and working principle of buoy were introduced.Then three model schemes are designed.The mathematical model of forced motion of buoy under incident wave was established and the numerical simulation was carried out.The hydrodynamic parameters such as additional mass,damping coefficient,wave excitation force and motion response of the buoy under the design condition were obtained.Finally,the capture width ratios of each design scheme under different periods were collected through physical model tests,and compared with those obtained by numerical calculation.The results show that the buoys of different design schemes adapt to different water depth conditions;The maximum value of capture width ratio of model 1 in the design scheme is 47.8%.
