摘　　要：本文以压电智能材料在振动控制中的应用为主线,针对风电机组叶片运转过程中的振动问题及产生振动后风电机组的主动控制问题进行研究。将压电材料的压电效应特性应用于风电机组叶片振动的主动控制中,对压电效应特性进行阐述、分析,与叶片振动的检测及主动控制进行结合,并通过Matlab中Simulink仿真工具箱对现场真实数据进行仿真模拟实验,实验结果表明利用压电陶瓷的压电特性与叶片振动的检测及主动控制相互结合的方法,对抑制风电机组叶片振动起到了明显的效果,最终实现对叶片振动的主动控制,达到减弱叶片振动的目的。This paper takes the application of intelligent materials in the piezoelectric vibration control of as the main line. It conducts research on wind turbine blades during operation of the vibration problem and the active vibration control problems after the wind turbine. Piezoelectric effect of piezoelectric material is applied in wind turbine blade vibration active control, elaborates and analyzes the characteristics of piezoelectric effect. The blade vibration detection and active control are combined, through Simulink toolbox in Matlab, the research takes simulation experiment and the result shows that the detection and active control methods combined with using piezoelectric ceramics blade vibration of the wind turbine blade vibration plays a significant effect. Ultimately it achieves the purpose of the active control of the blade vibration and also weakening the blade vibration.
