研究了单调谐质量阻尼器（TMD）对风力涡轮机叶片挥舞振动的被动控制。由于风切变，叶片受到的风压随着离地高度的线性变化。对风力涡轮机叶片的振动进行了理论分析和数值计算，得到了叶片的固有频率图、频率响应、平稳时程曲线及其FFT结果。研究发现，由于风压和参数激励项的共同作用，叶片响应曲线在比转速附近出现多个峰值。研究表明，如果利用不动点定理确定TMD参数的最优值，则最优单TMD可以抑制共振峰。分析了TMD质量和安装位置对TMD性能的影响。Copyright © 2014 by ASME
Passive control of flapwise vibrations of a wind turbine blade is investigated when a single tuned mass damper (TMD) is attached to the blade. The blade is subjected to a wind pressure which changes linearly with height from the ground level due to the wind shear. The vibrations of the wind turbine blade are theoretically and numerically analyzed to determine the natural frequency diagrams, frequency responses, stationary time histories and their FFT results. It is found that several peaks appear near the specific rotational speeds in the response curves for the blade because of both the wind pressure and the parametric excitation terms. It is also demonstrated that the optimal single TMD can suppress the resonance peaks if the fixed point theorem is used to determine the optimal values of the parameters of the TMD. The influences of the mass and install position of the TMD on its performance are also examined.Copyright © 2014 by ASME
