Abstract
In this study, we introduce how to detect broken wires in steel rope based on wavelet transform and virtual instrument technology. By means of the powerful data analysis function of virtual instrument and wavelet transform, the singularity of wires can be found and it could help to improve ability of locating broken wires and determining breakage grade.
Highlights
Hoisting rope is one of an important component of the lifting equipment and whose safe and reliable operation is important guarantee of production (Lee and Grimson, 2002)
It is known as Non-Destructive Testing (NDT) of wire rope, in which specific testing techniques and analysis methods may be applied to determine the state characteristics and Evaluation is given according to certain criteria (Cacciatore et al, 2007)
The principle of magnetic flux leakage detection method with simple principle, low cost, on-line detection ability, surface cleanliness without strict requirements and more suitable for the damage of wire rope made of good magnetic properties of carbon steel, which represents a unique advantage in the detection of broken wire rope and is more NDT method currently in the research and use of wire rope damage (Zhou, 2009)
Summary
Hoisting rope is one of an important component of the lifting equipment and whose safe and reliable operation is important guarantee of production (Lee and Grimson, 2002). The virtual instrument technology and wavelet transform which is used for characterization of signal mutation method is applied to the he detection and analysis for broken wires of wire rope, to improve the accurate ability to judge the position and size of broken wires (Zhou et al, 2011). It is known as Non-Destructive Testing (NDT) of wire rope, in which specific testing techniques and analysis methods may be applied to determine the state characteristics and Evaluation is given according to certain criteria (Cacciatore et al, 2007). By means of the powerful data analysis function of virtual instrument and wavelet transform, the singularity of wires can be found and it could help to improve ability of locating broken wires and determining breakage grade
