AE-based detection for magnetic tile internal defects: Integrating clustered symplectic geometry mode decomposition with one-dimensional convolutional neural network

2024 IEEE Far East NDT New Technology & Application Forum (FENDT)
This paper addresses the issues of low efficiency in manually detecting internal defects of magnetic tiles and instability in the detection accuracy by proposing an acoustic emission (AE)-based detection method that integrates symplectic geometry mode ...

Acoustic blade damage diagnosis based on improved symplectic geometry mode decomposition

Measurement science and technology
Wind turbine blades are vulnerable to damage due to coupled operational loads. Acoustic detection demonstrates strong potential for blade monitoring, but its performance is often hindered by complex noise and imbalanced monitoring samples. Accordingly,
