Abstract

Ultrasonic damage detection technology based on Lamb waves holds significant application value in the field of structural health monitoring for plate-like structures. However, due to the multimodal propagation characteristics of Lamb waves, their detection signals often exhibit complex features, which poses challenges for the effective extraction of damage information. To address this issue, this paper proposes a damage detection method for metal plate structures based on the construction of single-mode baseline signals using a mobile sensor setup. The innovation of the method lies in the adoption of a mobile sensor array composed of an excitation sensor and a receiving sensor, which constructs temporary baseline signals by measuring the signal responses of structurally healthy areas in real time. Based on these baseline signals, the system can accurately identify differences in structural response signals across different regions of the same structure. By calculating the difference between the current detection signal and the baseline signal, the damage scattering signal can be extracted. This study provides a new technical approach for the non-destructive testing of plate structures and shows promising potential for engineering applications.
