【Abstract】 The inevitability of radial random fluctuation that occurs during the quantitative inspection of broken strands and its effect on inspection when the electromagnetic flaw detecting method is used are discussed. In order to imporve the accuracy, a relation between "s", the distance from the surface of wi,re rope to Hall elements, and"VH" the Hall voltage output of the elements, has been obtained by simulation tests. The concept of a form factor ijs proposed and the software has been developed for error compensation for the radial random fluctuation. Test results show that the method proposed is effective.更多还原
