The influence of fin-shaped rod (FSR) with different installation positions on wind-induced vibration and energy harvesting of a cylinder-based aeroelastic energy harvester are studied by experiments and simulations. Two FSRs are installed symmetrically on the surface of a circular cylinder, and the coverage angle of each FSR is 20. The installation position of FSRs on the cylinder is represented by the placement angle, θ, which varies in the range of 160. And the tested wind speed range is 0–6.8 m s⁻¹. The results show that FSRs change the position of the separation point of the boundary shear layers, further affect the formation and shedding of vortices. Then the force on the cylinder changes, which causes the energy harvester to produce different vibration responses and energy outputs. When 0 < θ < 70, back-to-back vortex-induced vibration (VIV) and galloping can be observed for FSR-cylinder, and the output power increases with the increase of wind speed, the maximum output voltage and power reach 18.1 V and 1.645 mW. For 70 ⩽ θ < 120, the vibration of FSR-cylinder is suppressed, which is not conducive for energy harvesting. When 120 < θ ⩽ 160, the vibration of FSR-cylinder firstly experiences VIV and then galloping occurs after reaching the critical wind speed.

通过实验和仿真研究了不同安装位置的翅片形杆（FSR）对圆柱型气动弹性能量采集器风致振动和能量采集的影响。两个FSR对称地安装在圆柱体的表面上，每个FSR的覆盖角为20。FSR在圆柱体上的安装位置由放置角度θ表示，该角度在160的范围内变化。测试的风速范围是0–6.8 ms ^-1。结果表明，FSR改变了边界剪切层分离点的位置，进一步影响了涡旋的形成和脱落。然后，作用在气缸上的力发生变化，这导致能量收集器产生不同的振动响应和能量输出。当0 < θ <70时，FSR汽缸可观察到背靠背涡激振动（VIV）和驰gall，并且输出功率随风速的增加而增加，最大输出电压和功率达到18.1 V和1.645兆瓦。70⩽ θ <120，FSR-汽缸的振动被抑制，这是不利于用于能量收集。当120 < θ⩽ 160，FSR汽缸的振动首先经历VIV，然后在达到临界风速后才发生驰gall。
