摘要
Abstract
The Loss of Metallic Area(LMA)directly affects the bearing strength and other characteristics of the steel wire rope,therefore its detection and quantitative analysis are of great significance for the safe and reliable operation of the equipment.Aiming at the problems of difficult coil winding and fuzzy parameter determination in the current main magnetic flux detection,a split coil structure based on Printed Circuit Boards(PCB)is proposed based on the simulation model.The number of coils turns,coil layers,and other parameters in the design process are analyzed for their effect on the detection signal.Meanwhile,the main magnetic flux detection model is established to explore the influence of the defect width on the inductive voltage signal,and a compensation method is proposed for the signal loss caused by the reduction of the damage width.Finally,the steel wire bundle is used as an example to verify the quantitative detection of LMA.Experiment results show that the quantitative error of the proposed method is within 1%,and it can effectively detect the LMA of steel wire rope.关键词
