Abstract
Abstract: To address the issue of tower vibrations induced by wind loads, which can damage the structure of wind turbines, a vibration control method for monopile offshore wind turbine towers based on an eddy current-nonlinear energy sink (EC-NES) was proposed. The dynamic model of monopile offshore wind turbines based on EC-NES was constructed according to the Euler-Lagrange equation, and based on the output response of FAST software, the unknown parameters of the model and the wind loads were identified in terms of parameters. The optimal parameters of EC-NES stiffness and damping were obtained using PSO. The eddy current damper was designed based on these optimization results. The simulation results have shown that compared with traditional tuned mass dampers, the EC-NES device can effectively suppress the deflection angle of wind turbine towers, and it shows stronger robustness to the frequency change of the main structure.
