5.4 Conclusion
This paper makes a further improvement on the beamforming method. A new array
form and AE source location method is proposed. In order to verify this method
for the source localization, lead breaking experiment is simulated in finite element
analysis and verified on steel plate. Some conclusions are drawn based on analysis
of the localization results as follows:
(1) compared with linear array, X array has a larger localizing range and respectively
improves the localizing accuracy;
(2) as a supplement to beamforming, in the case of inaccurate localizing speed, the
vertical line method can greatly reduce the localizing error and help the damage
localizing of thin plate structure.
