| 摘 要： | 风力机叶片在风洞中作气动弹性实验的模拟方法、简化原理、模型设计原理和数据处理等有关问题及其弯曲／摆振颤振模型的地面实验和风洞吹风实验结果，文中都进行了讨论，根据模型实验的频谱和时域图，分析模型可能发生颤振的速度，用＂频率重合理论＂确定了模型的颤振点以及发生颤振时的颤振速度和颤振频率。

| Abstract: | in this paper, simulated method, simplified principle, design principle of the model and data reduction etc.Of aeroelastic experiment of the blade of the wind turbine in wind tunnel and experimental results are given. Experinimental results are emphatically discusscd, including ground testing results and experimental results in wind tunnel of bending/swinging buffeting model of the blade of the wind turbine. According to testing spectra and time graph of the model,it can determine speed at which the model can buffet.Using "coincident frequency theory" buffeting point, speed and frequency of the model are determined. |
