本文通过风洞实验研究了风对以正弦振型振动的圆柱体施加的功率。振动系统具有较低的阻尼比，结果表明，在振幅和输入功率的滞后现象。滞后的页已被解释相对于不同的流动模式在振荡圆柱的尾迹。比功率作为振幅的函数的结果与先前试验的中心组的结果一致。
This paper deals with a wind tunnel investigation of the power imparted by wind to a circular cylinder vibrating in a sinusoidal mode shape. The vibrating system has a low damping ratio and the results have shown a hysteresis phenomenon in both oscillation amplitude and power input. The sheets of the hysteresis has been interpreted with respect to the different flow patterns in the wake of the oscillating cylinder. The results of the specific power as a function of the vibration amplitude are in agreement with those of the central group of previous tests.
