Abstract: Steel wire rope core conveyor belt is a high-strength conveyor belt used for conveying materials,
widely used in mining, construction, metallurgy and other fields. However, after long-term operation of the steel wire
core conveyor belt, the internal steel wire rope may have defects such as breakage and wear, leading to equipment
damage during production and affecting production safety. In this paper, based on magnetic flux leakage detection
technology, damage detection of steel wire rope core conveyor belts was carried out. Firstly, a finite element model
for magnetic flux leakage detection of steel wire rope core conveyor belts with different types and cross-sectional
areas of damage was established, and the spatial distribution characteristics and variation rules of defect magnetic
flux leakage were analyzed. Then, magnetic flux leakage detection experiments of steel wire rope core conveyor belts
were carried out under laboratory conditions, and a combination of sliding average denoising and wavelet denoising
was used for signal denoising processing. The denoised signal can clearly display the severity of defect damage.
Simulation and experimental results showed that magnetic flux leakage detection technology can detect different types
and cross-sectional areas of damages in steel wire rope core conveyor belts, providing decision-making basis for the
use, maintenance, and safe operation of steel wire rope core conveyor belts.
