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。
Vortex-excited vibration energy conversion devices involve complex power coupling problems between flow-cylinder-generators. In this paper, the working mechanism of vortex-induced vibration energy conversion device is theoretically analyzed from three aspects of cylinder vortex-induced vibration, energy transfer and electric energy conversion, and relevant influence parameters are extracted, and the influence of flow, cylinder, generator three The dynamic coupling between them is analyzed, and it is confirmed that the similar parameters should be satisfied in the experimental simulation. In order to study the working characteristics of vortex-induced vibration energy conversion device under different water flow conditions, a set of experimental apparatus was designed and manufactured and the preliminary experimental results were analyzed.
