By comparing the structural characteristics of two traditional flexible hinges,a flexible mechanism con-necting the blades with the hub of the wind turbine is designed based on straight- beam flexible hinges.Then,a 3Dmodel of the whole wind turbine is established with SolidWorks,and a structural static analysis as well as a modalanalysis is performed with the finite element software ANSYS Workbench 14.0.The results indicate that the designedflexible wind turbine is more flexible than the conventional rigid one,and that the flexible connection between theblades and the hub remarkably reduces the natural frequency of the whole wind turbine,so that it helps to avoid thesympathetic vibration between the whole turbine and the blades,the tower or the wind rotor,protect the parts,andimprove the operation stability and life of the wind turbine.
