Development of new wind power generation method using wake galloping

为了开发一种利用串联圆柱体之间风致振动反馈放大的新型风力发电方法，进行了风洞实验。通过实验研究了两种反馈控制参数对振动特性的影响。当迎风圆柱振动时，振动幅值最大，时间滞后相当于背风圆柱特征周期的80%，并由控制增益规定，与风速无关。虽然振动幅度与控制增益成正比地增加，但这种增强在超过临界增益时会减弱。

In order to develop a new wind power generation method using feedback amplification of the wind-induced vibration caused between two tandem circular cylinders, wind tunnel experiments were conducted. The effects of two feedback control parameters on the vibrational property were investigated through the experiments. The maximum vibration amplitude is obtained when the windward cylinder is vibrated with the time lag corresponding to 80% of the characteristic period of the leeward cylinder, and prescribed by the control gain independently of the wind speed. Although the vibration amplitude is enhanced in proportion to the control gain, this enhancement diminishes beyond a critical gain.
