摘　　要：在分析钢丝绳状态检测已有的励磁方式的性能的基础上，针对大直径钢丝绳的特点，提出了二级励磁磁路结构．分析了二级励磁磁路结构的磁场特性，表明具有二级励磁结构的系统所获取的断丝信号信噪比高，无漏检，为断丝的定量识别提供了保证．Based on the Performance of existing magnetic methods for the condition monitoring ofthe steel wire rope, a new method using a two-step exciting field circuit structure is proposedin the light of the specific features of the steel wire rope with a large diameter. The fieldcharacteristics of the magnetic circuit are discussed.Theoretical and experimental investiga-tions show that with a new structure the SNR of the broken wire signal is high and no miss-ing has been found during detection.
