| Abstract: | A signal analytical model that applied in magnetic flux leakage(MFL) nondestructive test is researched.The model is based on dipole magnetic charge method.The radial and axial signals of three different defects are analyzed by this model.Test equipment and samples were designed and produced to make a MFL experiment,then,the results were compared with the simulated results of the analytical model.Good agreement between analytical and experiment results suggests that this model is effective in MFL signals analysis.The model gives the relation between defect size and MFL signals.It has the advantages of less factors,faster speed and convenient analysis and provides an important tool to MFL signal process and defect recognition and evaluation. |
