Gorkunov B. Development of theory and practice for implementation of devices controlling physical and mechanical materials characteristics using eddy current method

Investigation object: the process of interaction of the electromagnetic field with object of control, for reception of the information on physico -mechanical characteristics of metals. Target of investigation: creation of theoretically well-founded methods of functional synthesis of adaptive models eddy current transformers with the object, the physico-mechanical properties of metal products intended for reliable control. Investigation methods: the substantive theoretical provisions of work are based on fundamental principles of electrodynamics of continuous environments. For experimental researches of the developed eddy current transformers there were the used methods of physical design of the controlled parameters of metal products, methods of mathematical statistics of multivariable experiment and methods of the multidimensional mediated measurements. At carrying out of experimental researches applied the automated device for contactless eddy current control of metal products and eddy current the device to control of mechanical loadings in cylindrical products. Theoretical and practical results: the new technical decisions directed on increase of resolution of eddy current of devices which allow to supervise on one or two informative parameters changes of structure of a material at the is intense-deformed condition of a metal product are developed. New: the generalized physical and mathematical models and informative methods which result to increase of efficiency and reliability of control of objects of the technological and industrial setting are received. Degree of introduction: results of work are used for noncontact control of magnetic permeability and specific conductivity of continuous and tubular products, for the purpose of their grading under operational characteristics which are introduced on DP ВП "the Zaporozhye atomic power station" (Energodar). Sphere (branch) of use: the received theoretical and practical results can be applied to increase of efficiency of technical control at the enterprises of metallurgical, machine-building and electropower complexes.
