| 涡激振动能量转换装置涉及水流-圆柱-发电机之间复杂的动力耦合问题。本文从圆柱涡激振动、能量传递、电能转换三个方面对涡激振动能量转换装置的工作机理进行理论分析,提取出相关的影响参数,并应用量纲分析方法对水流、圆柱、发电机三者之间的动力耦合作用进行了分析,确定了实验模拟中应满足一致的相似参数。为了研究不同水流条件下涡激振动能量转换装置的工作特性,设计制作了一套实验装置,并对初步实验结果进行了分析。 |

| Hydrokinetic energy converter of vortex induced vibration (VIV) involves complex dynamic interaction among water current, cylinder and generator. In this paper, the working mechanism of vortex induced vibration energy converter was theoretically analyzed from following three aspects: the cylinder vortex induced vibration, the energy transmittion and the electric energy conversion. Relative parameters were extracted. The dynamic coupling of water current, cylinder and generator was analyzed based on dimensional analysis. The similar parameters used in simulation experiment were determined. In order to study the working property of vortex induced vibration energy converter under different water current conditions, an experimental apparatus was designed and fabricated, its preliminary experimental results were analyzed. |
