项目摘要
Vibrations of towers and blades of wind turbines were investigated and various methods were attempted to suppress them. From vibration analysis, the following two phenomena were clarified analytically. (1)Unstable vibrations of a wind turbine with a two-blade rotor which has an asymmetry of moment of inertia, and (2)Resonance phenomena and a mode localization of wind turbines.Concerning vibration suppression, the following three methods were attempted. (1)Vibration suppression of a wind turbine tower using a cylindrical tuned liquid damper, (2) Vibration control of floating structures utilizing gyroscopes.
对风力机塔架和叶片的振动进行了研究,并尝试了各种抑制方法。通过振动分析,解析地阐明了以下两个现象。(1)具有不对称转动惯量的双叶片风力机的不稳定振动;(2)风力机的共振现象和振型局部化。(1)采用圆柱形调谐液体阻尼器对风力机塔架进行振动抑制;(2)采用陀螺仪对浮式结构物进行振动控制。
