Damage identification of broken wires inside and outside the wire rope

open access: yesGong-kuang zidonghua, 2021
The wire rope broken wire damage detection is mainly focused on the outside broken wire damage detection, not on the inside broken wire damage detection. Moreover, the inside and outside broken wire identification accuracy is not high.

A Magnetic Field Concentration Method for Magnetic Flux Leakage Detection of Rail-Top Surface Cracks

open access: yesIEEE Access
Magnetic Field Leakage (MFL) is one of the prominent methods used to detect rail top surface cracks. However, it has been shown that detecting narrow rail top cracks is a major challenge because of their weak magnetic leakage fields.
