Abstract

In order to study the location of structural damage, an improved time-reversal (TR)-based ultrasound-probabilistic imaging (TRPDI) algorithm was proposed in this paper. The electrical signal was applied to the piezoelectric ceramics (PZT) attached to the surface of the aluminium plate to generate an ultrasonic Lamb wave with good propagation performance in the aluminium plate. Based on Lamb wave theory and TR theory, the damage index was optimized, and the damage imaging algorithm was used to analyze the damage degree of the specimen and locate the damage. Three different data processing methods were used to obtain the active components in the signal, and the damage existence judgment and damage location research were carried out, respectively. The experiments show that the TRPDI algorithm can improve location accuracy and has great application potential in engineering damage locations.
