Abstract

Journal of Vibration and Control, Ahead of Print.
To improve the accuracy and reliability of acoustic emission (AE) signal processing in wind turbine blade fatigue tests, this paper proposes a denoising method that combines singular value decomposition (SVD) and variational mode decomposition (VMD). The ...
