Abstract
For the problem of relationship between signal of tri-axial AC-MFL inspection and quantitative analysis of defects,a finite element of AC-MFL detection system was build by adopting Ansoft Maxwell program to simulate the 3-D static situation in the method of control variables.Results show that the change of defect length,width,depth and rotation angle will cause different magnetic field leakage signal.Three-axis magnetic flux leakage signal feature could be used for quantitative analysis of defects.In particular,it was shown that axial magnetic flux density had an important significance for quantitative analysis of complex defects.The results demonstrate the validity of the theoretical analysis.关键词
