Other AbstractWith the purpose of applying micromagnetic detection technology to nondestructive testing for wire ropes,the finite element method is used for analysis of the feasibility of the broken wire defects detection,using the residual magnetic field of the wire rope itself without extra magnetic field excitation. The wire rope defect points and the leakage magnetic field strength in surrounding air,distribution and the testability have been calculated. Then the influence of the geomagnetic field has been discussed,which is a theoretical basis for micromagnetic detection technology. Moreover, the testing results and the change laws in different broken wires states, as well as the functional relationship between the rope metal sectional area loss and the outputs of the detection system,are obtained through the experimental researches of micromagnetic detection method for wire ropes,that have verified the feasibility and reliability of micromagnetic nondestructive testing technology.
