【摘要】 为了解决风致振动能量采集器风向采集单一的问题，在圆柱涡激振动的基础上将翼型档板加在悬臂梁的另一端，翼型挡板感受方向带动圆柱体转动，实现随风向的改变而改变。翼型挡板还可以在风能的激励下发生颤振，提高悬臂梁的振动效率。运用Solidworks对风能采集装置的转动部件进行仿真，通过改变风速的大小分析转动部件不同位置在流体中所受压力和压强，保证装置在自然环境中正常工作。更多还原

【Abstract】 In order to solve the problem of single wind direction acquisition of wind-induced vibration energy harvester, an airfoil baffle is added at the other end of the cantilever beam based on the vortex induced vibration of the cylinder. The sensing direction of the airfoil baffle drives the cylinder to rotate to change with the change of wind direction. The airfoil plate can also flutter under the excitation of wind energy to improve the vibration efficiency of cantilever beam. The rotating part of the wind energy harvesting device is simulated by using the Solidworks, and by changing the wind speed, the pressure and the intensity of pressure on different positions of rotating parts in the fluid are analyzed to ensure that the device can work normally in the natural environment.更多还原
