| Abstract: | 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 energy-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. |
