22. Use of Metamaterials to Reduce Vibration of a Wind Tower Subjected to Arbitrary Stochastic Wind

The chapter delves into the application of metamaterials to mitigate vibrations in wind towers exposed to arbitrary stochastic wind loads. It begins by discussing the importance of renewable energy sources, particularly wind energy, and the challenges posed by dynamic loads on wind turbines. The study compares various vibration control methods, with a focus on metamaterials due to their feasibility and enhanced properties. The mathematical model used to assess the dynamic behavior of the turbine is detailed, including the tower-nacelle assembly and wind-induced forces. The analysis evaluates the performance of metamaterials in different resonator configurations and positions along the tower, targeting both low and high-frequency vibrations. The results showcase the effectiveness of metamaterials, especially for higher frequencies, and highlight the practical advantages over traditional methods like tuned mass dampers. The conclusion offers insights into the optimization and selection of vibration attenuation systems, emphasizing the potential of metamaterials for practical implementation in wind towers.
