摘　　要：通过仿真软件对常用的线圈励磁、线圈检测的励磁检测装置进行仿真研究。分析了励磁检测装置在采用不同结构形式时钢丝磁感应强度分布;研究了励磁装置中气隙大小、励磁线圈截面长宽比、电流大小及衔铁厚度等参数对被检测钢丝的感应强度分布的影响;对励磁检测装置进行了优化。仿真结果表明:优化后的结构所获得的磁感应强度满足预期要求,且稳定的磁感应强度区变宽。该研究对于选取合理的励磁检测结构和优化励磁检测装置设计具有指导意义。For the realization of the wire rope damage detection, we need to ensure uniform steady magnetic induction intensity in local wire rope.This article applies simulation soft electromagnetic analysis module and simulates several commonly used excitation test device. Analysis of electricity inside the solenoid magnetic field distribution under different structure forms. Excitation device was studied and the gas gap size, the solenoid coil section length-width ratio parameters such as size, thickness of the armature current, the induction strength of the tested steel wire rope and the influence of induction intensity distribution. There is profound guiding significance to the actual situation to select the reasonable structure of excitation test and modify the device parameters.
