The magnetic memory detection method is a damage detection technology, aims at the damage detection method of the magnetic leakage signal of the ferromagnetic material, and carries out detection based on the magnetic memory effect and the magnetic dipole model principle. The magnetic memory effect can be understood as: when the ferromagnetic component is acted by external force, due to the action of the earth magnetic field and the influence of the piezomagnetic effect, the magnetic domain organization of the stress concentration area can be reoriented and generates magnetic poles, so that the magnetic permeability is reduced, a leakage magnetic field is formed on the metal surface, the tangential component of the strength of the leakage magnetic field has the maximum value, and the normal component changes the sign and has a zero value point. This change in magnetic state remains after the workload is removed, memorizing the location of stress concentration, which is the so-called magnetic memory effect. The quantification of normal magnetic signals and tangential magnetic signals of a leakage magnetic field on the surface of a defect position in a stress concentration region can be realized by performing numerical integration on a magnetic dipole theoretical model, and the damage detection of a specific part is realized by analyzing the leakage magnetic field on the surface of the defect leakage magnetic field and obtaining the internal condition of the part.
The data analysis method adopted by the invention has two methods, one is to analyze and process the image by the algorithm of the control system 7, extract the image characteristics and classify the part types; the other method is a damage discrimination method of the magnetic memory signal, the two discrimination methods adopted by the invention are respectively magnetic leakage signal zero crossing point alarm and magnetic signal gradient threshold value alarm, and parts with zero crossing point phenomena of the magnetic memory signal and parts with gradients exceeding the threshold values are marked in a control system 7, so that the discrimination of the detected parts is realized.
In magnetic memory sensing technology, an important factor is the lift-off value of the probe, i.e. the distance of the probe from the part. Because the magnetic memory detection technology is influenced by other ferromagnetic parts when detection is carried out, the parts with mechanical structure functions are made of aluminum alloy materials, and the first conveying mechanism 1 and the second conveying mechanism 2 are made of rubber materials, so that the influence of external factors on detection signals is reduced to the greatest extent.
