| In order to promote the capability of design and manufacturing of wind turbine in China, more study should be done in the field of wind turbine design and analysis. In this paper, a blade for 2MW wind turbine is designed according to the traditional design procedure and the 3D geometrical model is created. Then the modal analysis is done through the FE simulation to get the frequency and mode shape, which provides the theoretic basis to prevent resonance. In addition, the static, modal and buckling analyses of the 2MW turbine tower are done to check its stress, displacement, mode shape and buckling parameter. At last, through the combination of FE simulation and optimization analysis, the geometrical parameters of the tower are optimized to reduce the weight and cost of the wind turbine. |
