Abstract	本申请公开了基于风致振动的压电能量俘获装置，以解决现有的低速压电能量俘获装置对环境风速适应性低的问题。本申请提供了基于风致振动的压电能量俘获装置，所述压电能量俘获装置包括第一翼型与第二翼型；以及连接件，第一翼型与第二翼型分别转动设置于连接件的两端，并分别与所述连接件形成夹角，本申请通过转动可以调整第一翼型以及第二翼型在所述连接件的夹角，进而调整第一翼型以及第二翼型的攻角，本申请通过设置攻角可调的双翼型钝体结构，实现装置的不同攻角对应不同的流致振动机理，进而适用于不同风速下的风能俘获和利用，也就是综合利用两种振动在低、高速下的振动的优势，即低风速下涡激振动，高风速下驰振，输出的综合性能得到提高。
Other Abstract	The invention discloses a piezoelectric energy capturing device based on wind-induced vibration. The piezoelectric energy capturing device is used for solving the problem that an existing low-speed piezoelectric energy capturing device is low in environment wind speed adaptability. The invention provides a piezoelectric energy capturing device based on wind-induced vibration. The piezoelectric energy capturing device comprises a first airfoil profile and a second airfoil profile, the first airfoil profile and the second airfoil profile are rotationally arranged at the two ends of the connecting piece correspondingly, and included angles are formed between the first airfoil profile and the connecting piece and between the second airfoil profile and the connecting piece correspondingly, the included angles of the first airfoil profile and the second airfoil profile on the connecting piece can be adjusted through rotation, and then the attack angles of the first airfoil profile and the second airfoil profile are adjusted; by arranging the double-wing bluff body structure with the adjustable attack angles, different attack angles of the device correspond to different flow-induced vibration mechanisms, and then the device is suitable for capturing and utilizing wind energy at different wind speeds, that is, the advantages of two kinds of vibration at low and high speeds are comprehensively utilized, namely vortex-induced vibration at the low wind speed and galloping at the high wind speed are comprehensively utilized; and the output comprehensive performance is improved.
