Petukhov I. Quasi-stationary electromagnetic field in nonlinear solid and conductive media (numerically-harmonic analysis)

The оbject of research: quasi-stationary electromagnetic field in inhomogeneous nonlinear solid and conductive media. The purpose of research: development on the basis of mathematical modeling methods for analysis of quasi-stationary electromagnetic field, taking into account the magnetization, hysteresis, motion of media and heat generated from eddy currents, which allow to increase the accuracy of the results. Methods of research: mathematical modeling, analysis of the influence of media parameters on the distribution of the electromagnetic field, the comparison of the results of solving these problems with known solutions available ones closely related objectives, as well as with experiment. Theoretical and practical results and innovations: it was solved an important applied scientific problem of raising the level of adequacy of the modeling of quasi-stationary electromagnetic field in nonlinear solid media through the development of numerical harmonic analysis methods that have improved the accuracy of estimation of the instantaneous characteristic values of the field and the integral electromagnetic parameters. Developed analysis methods and mathematical models designed in the form of a program GE2D. A subject degree of introduction: The software GE2D is used in the research Institute "Kvant" (Kiev), in the three departments of the Institute of electrodynamics of NAS of Ukraine, the results are used in the Institute for metal physics of NAS of Ukraine, JSC "Novokramatorsky machine-building plant", the plant "Analog" (Vinnytsia). Effectiveness of implantation: software solves the problems of modeling, the accuracy of which was not possible by other means. The study of indicators of perspective models of new units was made., some of ones is production run equipment. Sphere of use: electrical engineering
