摘　　要：为了提高中心管振荡水柱波浪能发电浮标的能量转换性能,将发电浮标中心管尾部由直管整体替换为锥度101°的锥形管,在造波水槽中进行模型试验。实验研究发现:在规则波条件下,俘获宽度比最高可达到65.09%,并且存在一个较宽的通频带;在随机波条件下,俘获宽度比最高可达50.16%。在所有获得宽通频带结果的试验中,所测得的波浪能量转换特性优于历史文献结果。根据试验结论设计多款小型海洋仪器发电浮标样机,设计的样机具有较高的性价比。For improving the energy conversion efficiency of center-pipe oscillating water column(OWC)wave power generating buoy,a new design of the center-pipe buoy was considered in this work,where original straight center-pipe is replaced by the cone tail pipe with a taper of 101°. The model of the new buoy is implemented to test the wave energy conversion performance in wave tank. The results of this experiment show that the maximal capture width ratio(CWR)of the model is 65.09% and has broad bandwidth under regular wave and the maximal CWR of the model is 50.16% under random wave. Among the broad bandwidth experimental results,the measured wave energy conversion characteristics of the model is superior to the historical results. According to the test results,several kind of small marine instrument wave energy generating buoys are designed. The designed prototypes have high cost effective.
