Description

technical field [0001] The invention belongs to the technical field of steel wire detection, in particular to a steel wire damage detection experimental platform based on magnetic memory signals. Background technique [0002] Existing detection methods for steel wire mostly use X-ray, ultrasonic, magnetic powder, eddy current, γ-ray, penetration, magnetic flux leakage and other methods, but these methods have certain shortcomings, such as: special magnetization device is required, and the surface needs to be cleaned ; Coupling technology is required; stress concentration parts cannot be detected quickly and accurately; steel wire defects cannot be effectively detected, and defects that will occur in the future cannot be predicted. [0003] At present, there is no complete experimental platform for steel wire damage detection, which is used to detect the damage degree and damage location of steel wire. Since the service environment of the steel wire is carried out under a ce...

AI Technical Summary

Problems solved by technology

Since the service environment of the steel wire is carried out under a certain tension condition, the magnetic memory signal of the steel wire is collected and processed. During the collection and processing of the magnetic memory signal, the existing device cannot strictly control the distance between the sensor and the steel wire and the moving speed of the sensor. , to ensure the rigor of magnetic memory signal collection
