Description
Nowadays the wind energy markets continue to grow to accommodate the current demands of renewable energy. As the wind turbine blades are susceptible to suffer damage from complex and irregular loading caused by catastrophes, development of quick and reliable ways for wind turbine health monitoring is becoming crucial. Natural frequency testing is one of the most commonly used non-destructive health monitoring methods, as any damages could lead to changes in the structural vibration characteristics. In this paper, a series of tests were carried out to measure the natural frequencies of a 13 m wind turbine blade. Various testing techniques and devices were employed in this study and the accuracy of the acquired data, namely the captured accelerations and the corresponding Fast Fourier Transform (FFT) diagrams, were compared. The advantages and disadvantage of the three techniques were discussed.
