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