In order to improve the excitation effect of steel rope core conveyor belt non-destructive testing device,a new excitation device structure combining axial excitation and radial excitation was proposed.The key parameters of the new excitation structure were optimized based on theoretical model and finite element analysis.The simulation results show that the optimized design of the new excitation structure increased the magnetic line density inside the steel rope core compared with the traditional structure.The maximum magnetization of the steel rope core conveyor belt is increased by about 4.18%,and the saturation excitation length is increased by about 21.28%.The excitation effect is better than the traditional excitation structure.
