Hardware-software system for magnetic analysis of structure

Abstract

The relative values of the magnetic properties of a substance is shown to be determined locally by measuring the magnetic field induction in the transducer hole of a special form made in the magnetic circuit of the measuring transducer and the tangential component of the magnetic field in the interpolar transducer space near the surface of the magnetized object.The proposed method is shown to allow for the determination of the whole complex of hysteresis characteristics and significantly expand the ranges of measurement of magnetic properties.The difference in the structural sensitivity of the magnetic properties locally determined in the coordinates "flow-internal field" (properties of matter) and in the coordinates "flow in the product-current in the windings" (properties of the "body") is established.The possibility and expediency of simultaneous measurement and pooled analysis of the magnetic characteristics of the substance and the "body" is shown.Information about the mobile hardware-software system DIUS-1.15M, designed to implement one-and multi-parameter methods of monitoring the structural-phase and stress-strain state of ferromagnetic materials and objects based on the proposed measurement techniques is provided. © Published under licence by IOP Publishing Ltd.
