| 摘 要： | 应用ONERA气动力模型对挥舞一摆动耦合风力机叶片进行颤振分析，数值分析采用NACA0012叶型的风力机叶片数据，根据数值积分得到叶片自激振动的时间响应曲线，由此容易判别在给定风速下，叶片的气动弹性稳定性。研究结果为动力失速状态下叶片稳定性的分析与判别提供了一个可选择的途径。

| Abstract: | The flutter of blades in wind turbine subjected to the flap/lead-lag motion coupled is analyzed by the application of the ONERA aerodynamic model in this paper.The numerical analysis is carried out by using the data from blades in the wind turbine with a type of NACA0012.The time-response-curve of the blades with self-induced vibrations is obtained by numerical integration. At last,the aeroelastic stability of the blades is easy to be determined on the basis of the above results under the given wind speed. |
