Study on Vibrations of a Wind Turbine and Its Suppression

首先，研究了旋转刚性叶片和旋转柔性叶片对转速的响应。阐明了叶片重量激振与随高度变化的风激振的协同效应。其次，研究了双叶式水轮机塔架的不稳定振动。最后，研究了流体阻尼器对塔架振动的抑制效果。

First, responses of a rotating rigid blade and a rotating flexible blade to the rotational speed were investigated. The synergetic effect of the excitation due to the blade weight and that due to wind which varies by height was clarified. Next, an unstable vibration of a tower with a two-blade turbine was investigated. Finally, the suppression effect of a fluid damper to the tower vibration was investigated.
