They play a crucial role in capturing wind energy and converting it into mechanical energy, which is then converted into electrical energy by the generator. A wind blade is a thin shell structure made of composite materials, consisting primarily of three parts: the root, the outer shell, and the keel. Blades are typically designed with a circular cross-section to facilitate rotation and withstand wind forces. The root is connected to the hub and serves as the connection between the blade and the wind turbine. During the operation of a wind turbine, vibration data on the wind blades must be collected.
