Influence of the Size of Damage to the Steel Wire Rope on the Magnetic Signature

Abstract

This article presents diagnostic tests of wire ropes using passive magnetic methods. The study used two types of wire ropes with different constructions and diameters. Defects of various depths were modeled in the ropes, which reflected the degree of loss of metallic cross-section. After a series of measurements, a correlation was observed between the amplitude of the module signal and the degree of damage to the rope. The signals were recorded with the advantage of the SpinMeter-3D magnetometer. The obtained results were subjected to the extraction of features, the analysis of which allowed the damage to be identified.

Use of Different Types of Magnetic Field Sensors in Diagnosing the State of Ferromagnetic Elements Based on Residual Magnetic Field Measurements

“…[40] proposed an approach to assess defects using the peak value of the magnetic signal's normal component Hp(y). These assumptions were confirmed in [42], where the depth of damage was dependent on the amplitude of the diagnostic signal. A detailed signal analysis with promising conclusions was presented in [43].…”

Trends in the Growth of Damage Extents in a Steel Conveyor Belt’s Core

“…The most commonly used non-destructive methods in the diagnostics of conveyor belts include vibration analysis [48][49][50], thermography [51,52], magnetic method [53,54], and ultrasonic method [55]. These methods allow for the detection of failures, cracks, or other defects that may be invisible to the eye during visual inspection.…”

A Comprehensive Review of Steel Wire Rope Degradation Mechanisms and Recent Damage Detection Methods

“…They have been successfully used both to assess the strain in wire ropes due to bending and to detect broken wires. They allow qualitative and quantitative assessments [99,100]. The main types of sensors in the field of passive magnetic diagnostics are magnetoresistive and optically pumped sensors.…”
