文摘
- •
A processing framework based on Hilbert–Huang Transform (HHT) for Acoustic Emission (AE) data is proposed.
- •
The use of HHT gives rise to a superior denoising properties.
- •
Reliable identification of P- and S-wave and robust AE parameters estimation.
- •
Multilateration (MLT) achieves accurate analysis of crack evolution and propagation speed estimation.
- •
The results show the potential application of the framework for Structural Health Monitoring.
