“…Harte et al [6] established the coupling model of the wind turbine; then the modal was analyzed under different loads. The modal of composite blades was analyzed in the case of the fluid structure interaction by Kang et al [7]. Cortínez and Piovan [8] developed a theoretical model for the dynamic analysis of composite thin-walled beams with open or closed cross sections.…”

This paper presents a structural optimization design of the realistic large scale wind turbine blade. The mathematical simulations have been compared with experimental data found in the literature. All complicated loads were applied on the blade when it was working, which impacts directly on mixed vibration of the wind rotor, tower, and other components, and this vibration can dramatically affect the service life and performance of wind turbine. The optimized mathematical model of the blade was established in the interaction between aerodynamic and structural conditions. The modal results show that the first six modes are flapwise dominant. Meanwhile, the mechanism relationship was investigated between the blade tip deformation and the load distribution. Finally, resonance cannot occur in the optimized blade, as compared to the natural frequency of the blade. It verified that the optimized model is more appropriate to describe the structure. Additionally, it provided a reference for the structural design of a large wind turbine blade.
