Defect in S45C cylindrical component was evaluated by using fluxgate (FG) magnetic sensor, which could measur e the order of 10 T magnetic flux density. Changes in magnetic flux densities were measured around a defect i n a plain cylinder component. In order to analyze defect shape and size quantitatively, the relationship betwe en magnetic flux densities and magnetic dipole moment of the defect plane in cylindrical component was formul ated. And the inverse analysis of Tikhonov regularization technique wa...

flux gate sensor inverse analysis magnetic dipole magnetic flux leakage non-destructive evaluation Tikhonov regularization
In this paper, an improvement technique for non-destructive evaluation using magnetic flux leakage is presented. It is indicated that the magnetic flux density varies steeply around defects. The response function which associates magnetic dipole and magnetic flux density in terms of geometrical coordinate is improved in order to catch the average value of magnetic flux along sensor length instead of locally-restricted value. The effect of that improvement is verified in the scheme of numerical simulat...

Defect in a stud bolt was evaluated by using fluxgate (FG) magnetic sensor. In order to analyze defect shape and size quantitatively, the relationship between magnetic flux densities and magnetic dipole moment on the defect plane was formulated in cylindrical coordinate system. Periodicity was observed alonglongitudinal direction in magnetic flux density distribution measured by fluxgate magnetic sensor. The inverse analysis based on Tikhonov regularization technique was performed by using magnetic flu...

inclined crack inverse analysis magnetic dipole moment magnetic flux leakage technique welding part
The technique of obtaining shape of inclined defect at heat affected zon e for welded specimen of high chromium steel was proposed. In this techn ique, magnetic flux leakage measurement and the inverse analysis using s ingular value decomposition were used. Suitable defect shape was obtained from the magnetic flux density distribution under the high magnetic fiel d without being subject to the influence of a welding part. Under the lo w magnetic field, suitable defect shape was obtained by subtracting the ...
