The possibility of application of the Infolytica software package to solve the main tasks of work is substantiated. The computer 3D-model of electromagnetic separator was verified by solving of test problem. Comparison of results of magnetic induction research for characteristic points obtained during 3D modeling of electromagnetic separator with data obtained during experimental research showed a fairly high consistency. An analysis of geometric dimensions influence on distribution of magnetic field in a polygradient matrix was carried out for a random sampling containing three structural variants of an electromagnetic separator, the working air gap of which varies over a wide range. It is shown that determination of magnetic flux distribution for other structural variants of matrix that located inside sampling can be carried out by interpolation. For selected variants, three-dimensional computer models of electromagnetic separator are developed, their geometric characteristics and physical properties are described. A numerical-field analysis of magnetic field spatial distribution in working air gap of polygradient matrix of electromagnetic separator was carried out using Magnet module of Infolytica software package. For three threedimensional models of electromagnetic system of separator, numerical values of magnetic induction and magnetic flux in working air gap of polygradient matrix in center of characteristic area are obtained. The obtained results for three models are compared and variant with rational parameters of working area of separator matrix is selected. |
