Research on simulation design of wire rope detection sensor based on permanent magnet excitation

Binghua Chen and Shangkun Ren

Abstract: 

Permanent magnet excitation is the current mainstream excitation method for wire rope defect detection.Use Maxwell finite element simulation software to simulate the structure of the yoke in the permanent magnet excitation mode, and construct the optimal excitation structure through the analysis of the simulation data; The relationship between the placement height of the magnetic sensor and the change of the leakage magnetic field under the excitation structure is analyzed; The changes of leakage magnetic field under different defect lengths and different defect depths are studied; The change of the leakage magnetic field when the excitation structure is jittered is analyzed; And use matlab to fit some of these changes. The analysis of these data can play an important role in the development of detection probes for permanent magnet excitation.
