摘要：
To meet the needs of safety assessment of large and complex plate structures, a Lamb wave health monitoring technique for stiffened metal plate structures based on compressed sensing is developed. The dispersion characteristics of Lamb waves in stiffened panel structures are recovered from a small amount of testing data obtained from sparse array using compressed sensing technology. To realize large-scale defect detection imaging in stiffened panel structures, a new method of sparse array Lamb wave composite imaging combining cosine similarity with Pearson similarity is proposed. The experimental results show compressed sensing technology can recover the frequency-wavenumber relation of Lamb waves in stiffened plates. And the Lamb wave composite imaging method can detect and locate single and multiple defects in stiffened panels. Research work provides a feasible technical solution for detecting damage of complex plate structure. © 2019, Press of Chinese Journal of Aeronautics. All right reserved.
