摘　　要：以双馈变速恒频风力发电机组两种传动链动力学为研究对象,应用拉格朗日能量法及多体动力学基本原理,建立两种传动链的动力学模型,分析主轴轴承数目的变化和齿轮啮合时弹性变形引起的固有频率的变化,为风力发电机组的设计和应用提供理论依据和技术支撑。In the paper,base on the dynamics modeling method of the doubly-fed variable speed constant frequency wind turbine drivetrain, two dynamics models of the drivetrain are built according to en- ergy-based Lagrange law and the theory of mulibody system dynamics. The natural frequency, which is affected by changes of the number of principal axis bearings and elastic deformation of the gear pairs, are analyzed. A theoretical basis and technical support are given in the wind turbine designs and applications.
