Abstract

Purpose. To investigate the dependence of the magnetic properties of a material on its chemical composition obtained at different pressures at certain temperatures. On the basis of the specific composition and properties of this material, to investigate how its operating points and loss of re-magnetization change, which in turn will affect the structural and operational characteristics of the magnetic damper of engine.

Methodology. Selection of the function extrema of the magnet energy dependence on induction and intensity through differentiation of expression, calculation of operating points of the magnet by the method of selection and using the MathCad medium, determination of the energy of re-magnetization through the integration of hysteresis loops, analytical calculation of magnetic forces in a magnetic damper using Beamer experiment formulas..

Findings.In the course of this task the operating points of the magnet hysteresis loop were determined, in which the magnetic energy is greatest by differentiating the expression of the dependence of the magnet energy on induction and intensity. On the basis of these data, the maximum magnetic induction was found to be the tertiary force of the magnetic field at these points. These points characterize the highest specific energy of the magnet, which is further used as intended. Then, based on the hysteresis loop, the energy of losses on the re-magnetization of the magnet was found by integration. According to these data, the unloading force of the magnetic damper was calculated.

Originality. More accurate analysis of magnetic processes in magnetic materials was conducted using a mathematical apparatus, software environments such as MathCad, OriginLaB. The dependence of the material magnetic properties on its chemical composition, energy and losses is analyzed, which in turn makes the use of a permanent magnet more efficient in engineering, apparatus and machines.

Practical value. According to the obtained results of calculation of energy losses and operating points of the magnet, the optimal chemical composition, its geometric size is determined, which allows to reduce production losses, save materials while increasing the efficiency of magnetic material in engine design. This increases both operational life of the machines and their reliability.  The optimum dimensions of the magnets in the windings provide the required air gaps, which in turn, due to the absence of friction, reduce losses increasing the unloading force.
