Description

Technical field

[0001] The invention relates to the technical field of non-destructive testing, in particular to a hydraulic tight ultrasonic guided wave damage detection device facing a stranded wire structure. Background technique

[0002] Metal stranded wire is a slender structure formed by spirally twisting one or more layers of single wires around a center line. It has the advantages of high strength, superior electrical performance, and strong carrying capacity. It is often used as an effective load-bearing component and is widely used in bridges. In large-scale environments such as ports, railways, and buildings, the health monitoring of stranded structures has become a research hotspot at home and abroad.

[0003] At present, researches on defect detection for stranded wire structures have been carried out at home and abroad, and non-destructive testing techniques are mainly used to detect the internal and external structure and mechanical strength of stranded wires. Accord...
