Design and simulation of wire rope damage detector based on hybrid maglev

Electromagnetic testing is the most widely used technology for wire rope inspection. However, with the existing technology, there are still some problems in practical applications; one of the urgent needs to solve the problem is how to suppress the relative fluctuations of the wire rope and detector. To solve this problem, a wire rope damage detection device (WRDDD) based on hybrid maglev is developed. First, the control force and key structural parameters of the WRDDD based on hybrid maglev are analyzed using theoretical formulas. Then, the effect of current on the excitation magnetic field of the wire rope is analyzed using the finite element method. Finally, the correctness of the WRDDD is verified by comparing the difference between finite elements and theoretical calculations in the current-force relationship, which shows extraordinary advantages for the inspection of wire rope.
