内置压电悬臂梁的涡致振动圆管俘能结构实验研究
Experimental Study on Vortex-Induced Vibration Tube Energy Harvesting Structure with Built-in Piezoelectric Cantilever Beam
摘要
Abstract
Using computer simulation and water cycle test system,the performance of vortex-induced vibration energy capture structure of flexible circular tube with built-in piezoelectric cantilever beam is analyzed under the condition of resistance fluid diameter,diameter ratio and double energy capture structure in series.The results show that the output voltage of the energy harvesting structure increases with the increasing of diameter of the cylindrical resistance fluid,and increases first and then decreases with the increasing of pitch-to-diameter ratio.When the diameter of the resistive fluid is 0.03 m,the height is 0.05 m,and the inter-diameter ratio is 3,the optimal output voltage peak-to-peak is 5.83 V.When the two energy harvesting structures with the same parameters are placed in series,the output voltages of the two are very different,and the output voltage of the second energy harvesting structure is much larger than that of the first energy harvesting structure.Considering the voltage values of the two energy harvesting structures,when the inter-diameter ratio is 4,the voltage values generated by the two structures are 0.71 V and 5.24 V,respectively,which is better than the other values.关键词
