Estimated mathematical model of cracks in magnetic inspection of railroad rails
A model of crack was developed to provide possibility for magnetic field over the defect, and signal that will be inducted in the searching coil depending on its parameters, spatial orientation and height above rail head to be calculated. This allows to analyze the shape of the signals and the ratios between their amplitudes for all three components of the magnetic field caused by crack depending on its shape and location in the rail and to predict signals in multichannel systems of rail flaw detection.
