NDE and SHM of Critical Parts using Magnetic and Electromagnetic Methods

Abstract

The paper has been intended to introduce a complex research problem, that is present in aviation, power engineering, mining and transport, with regard to assurance of operational safety for ageing technology, which is exposed to different form of material degradation. Theoretical reasons of non-destructive evaluation (NDE), structural health monitoring (SHM) and active control of material fatigue have been outlined. The magnetic and electromagnetic methods of NDE and SHM such as metal magnetic memory, low frequency eddy current spectroscopy, Barkhausen noise and 3MA have also been presented. The topic has been illustrated by means of practical examples.

Improving the effectiveness of the DiagBelt+ diagnostic system - analysis of the impact of measurement parameters on the quality of signals

“…Devices utilizing magnetic properties are also available, both for diagnosing belt cords and for diagnosing steel wire ropes [27,34,35]. The device [41], operating similarly to the DiagBelt+ system analyzed in the article, aggregates the obtained signal from a 40 cm width of the belt into a single measurement channel, thereby preventing the identification of individual failures. The research described in the article showcases the magnetic system DiagBelt+, its application for measurements under various parameters, and the obtained measurement results.…”

Impact Damage Detection in Laminate and Honeycomb CFRPs using Lamb Wave Ultrasonic Sensing

“…The scientists and engineers examine various physical principles to be utilized in SHM: vibration [5][6][7], ultrasonic waves [8], thermography [9,10], eddy currents [11,12], electromagnetism [13], etc. In the case of aerospace the SHM development task is more complicated due to hard limitations of the aircraft weight: the installed sensors, wires, and electronics can nullify the advantages of SHM application [14,15].…”
