摘要

针对IEA-15 MW风力机

采用自由涡尾迹模型和几何精确梁模型

对其在浮台运动下进行研究气弹响应研究。研究结果表明

浮台的横摇运动会造成叶片入流的波动

且对叶片的切向入流的影响更为显著;入流速度的波动会导致风力机载荷的波动

同时

各叶片间入流速度变化的差异将进一步产生风轮俯仰及偏航力矩;横摇工况下叶片形变将出现显著波动

由于横摇运动可大幅改变叶片的切向入流速度

因此摆振形变的幅值相较于挥舞和扭转形变更大

此外叶片的扭转变形会降低叶片攻角;浮台的运动会导致风轮尾迹畸变

叶片形变会减弱尾迹畸变的同时加剧尾迹的径向膨胀。

Abstract

In this paper

the aeroelastic characteristics of IEA-15 MW wind turbine under roll condition are studied by using the lifting-line free vortex wake model and geometrically exact beam theory model. The results show that the roll motion of the floating platform causes the fluctuation of blade inflow

and the effect on the tangential inflow is more significant. The fluctuation of inflow velocity will lead to the fluctuation of wind turbine loads. In addition

the difference of inflow velocity between blades will lead to the tilt and yaw moment of wind turbine. Under roll condition

blade deformations will fluctuate significantly as the tangential inflow velocity of the blade will be significantly changed by roll motion

the amplitude of the edgewise deformation is larger than that of flapwise and torsional deformations. In addition

the torsional deformation of the blade will reduce the angle of attack of the blade. The motion of the floating platform may cause the wake distortion of the wind turbine

and the blade deformations may weaken the wake distortion and intensifies the radial expansion of the wake.
