“…Moreover, D 33 represents the electric permittivity constant. Finally, k sc is the shear correction coefficient which is taken equal to 5 6 . The constitutive equations governing the behavior of elastic beams can be derived by setting their piezoelectric constants For a thin piezoelectric layer that is polarized in the thickness direction, the dominant component of the electric field can be expressed as…”

Many countries have a variety of offshore and onshore wind turbines that face extreme aging challenges. Issues with harmful vibrations that must be minimized are addressed in this paper. A new method of wind turbine tower vibration control using piezoelectricity and shunt circuits is proposed in this paper. The passive vibration control method is shown to improve the tower’s structural performance under various environmental loads, like wind and seismic excitations. To examine the effectiveness of the suggested shunted piezoelectric system, a simple surrogate finite element model of a wind turbine tower is considered, and various investigations at the second eigenfrequency are carried out. An alternative way of modeling the studied structure is considered and the results demonstrate better performance. The advantages of setting up structural damping systems for decreasing tower vibrational loads and boosting their structural stability and resilience against extreme events are highlighted throughout this work.
