Vibration-based damage identification in wind turbine tower by FBDD method

This paper presents a numerical evaluation of vibration-based structural damage assessment in wind turbine tower (WTT) structures. Firstly, a frequency-based damage detection (FBDD) algorithm is described to nondestructively locate the damage in the tower structure of wind turbines. Secondly, a finite element model of a real WTT structure is established by using a commercial software, midas FEA. Several damaged scenarios are studied on the numerical model of the WTT in which the stiffness of simulated damage location is reduced. Finally, the applicability of the FBDD method for the tower structure of wind turbines is numerically evaluated. The location of structural damage on the WTT are identified during the detecting process.
