1基于B-L气动模型的旋转水平风机叶片经典颤振稳定性分析显示文摘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。李迺璐 穆安乐 Balas M J 2015振动与冲击2015,34,23:9
2基于Floquet理论的旋转风机叶片动力失速气弹稳定性研究显示文摘研究旋转风力机叶片动力失速气弹稳定性问题。叶片结构采用标量化的挥舞和扭转自由度耦合的振动运动模型,旋转风机叶片的气动力由Beddoes-Leishman失速模型来模拟,通过攻角在深度失速区域内的变化来计算出周期时变的非线性气动失速负载。在系统静平衡点附近对非线性气弹系统进行线性化,采用Floquet理论分析旋转叶片动力失速气弹稳定性,其结果得到系统时域响的验证。通过数值分析,揭示了挥舞扭转固有频率比和结构阻尼对颤振边界的影响。李迺璐 穆安乐 Balas M J 2015振动与冲击2015,34,24:4
