摘要：In this paper, the 2MW generator system is taken as an example. Firstly, the modal frequency of the system is obtained by theoretical calculation, FEA analysis and experimental test. The comparison of the three methods shows that the system frequency is calculated by using the mass point and rigid beam simplified generator model. It has a certain reliability, and greatly simplifies the selection of the elastic support of the wind turbine. Secondly, the DOE method is used to analyze the sensitivity of the wind turbine’s elastic support stiffness by the integration of ABAQUS and Isight software. Finally, the stiffness is optimized by algorithm. This is the first time that the method of designing the elastic support for wind turbine is deeply studied, which provides a scientific reference for the reasonable selection.
