摘　　要：碳纤维复合材料具有强度高、模量高、质量轻、耐疲劳等特点。针对风力发电机叶片的振动特性及变形形式,设计了碳纤维复合材料风力发电机叶片,并采用ANSYS有限元分析软件对叶片进行模态分析,得到了碳纤维复合材料风力发电机叶片的固有频率。与相同结构的树脂叶片进行对比,结果表明碳纤维叶片固有频率高于树脂叶片的固有频率。对碳纤维叶片进行模态实验,实验结果与仿真结果的误差较小,可为碳纤维复合材料风机叶片提供设计依据。Carbon fiber composites are of high strength,high modulus,light weight,fatigue resistance.According to the characteristics of wind turbine blade vibration and deformation form,the carbon fiber composite wind turbine blades were designed.The finite element analysis software ANSYS was used to simulate the blade,and the natural frequency of the carbon fiber composite wind turbine blades was obtained.Compared with the resin blade for comparison,the natural frequency of the carbon fiber composite blade is higher than the blades′.Carbon fiber blades modal experiment was performed,and the experiment results and simulation results are similar.
