This text proceed with the theory of the vibration, utilize typical elastic hinge law analyze structure dynamics characteristic when the blade is quivered to instability, and then use relevant knowledge of blade vibration to simplify the model and the aerodynamic force of the vibration. Through the simplification, we can get the equation of the blade, which is dispersed to its instability. Then VISUAL BASIC procedure is utilized to work out thecharacteristic value of vibration and the vibration frequency. At last comparing the result which is calculated by the above-mentioned theory formulae with the result which is calculated by internationally agreed procedure ANSYS to verify the accuracy of the formula of reduction.

本文从振动理论入手，利用最为典型的弹性铰链法分析叶片发生颤振失稳时的结构动力学特性，然后对振动模型及振动时所受的气动力进行简化，利用简化方程得到叶片发生发散失稳时的振动方程，利用编制的VISUAL BASIC程序解出振动的特征值并得到振动频率，最后分别通过上述的理论公式和国际通用的有限元程序ANSYS对风力机叶片模型进行发散失稳时的频率计算，验证简化公式的准确性。
