摘要

研究旋转水平轴风力机叶片周期时变气弹系统的经典颤振稳定性特性。叶片结构采用了具有挥舞和扭转耦合的典型界面振动模型，引入Beddoes-Leishman气动模型为旋转叶片提供低攻角处周期时变的非定常气动力。为了研究颤振边界，利用标量风速和挥舞/扭转固有频率比对所建立的旋转叶片气弹模型进行变型。在此基础上，通过时域响应曲线分析旋转叶片挥舞自由度和扭转自由度气弹稳定性特性，分析了标量速度，叶片刚度，挥舞/扭转固有频率比和结构阻尼的影响，揭示了旋转叶片经典颤振边界的变化规律且其准确性得到验证。

Abstract

Aeroelastic characteristic of the rotating horizontal axis wind turbine blade is studied for classic flutter. The structural model of the blade is a classic vibration system, with two degree of freedom (flapwise and torsional blade oscillation), and periodic time-varying aerodynamic loads offered by Beddoes-Leishman dynamic model at the low angel of attack. The normalized structural model, is used to analyzed the effect of normalized wind velocity, blade stiffness, ratio between flapwise and torsional natural frequencies and blade damping on the aeroelastic stability of the rotating blade. The flutter boundary is found to reveal the characteristics of classic flutter of the rotating blade.
