Criteria-Parametric Analysis of the Magnetic Core Geometric Dimensions Influence on the Operating Mode of the Device for Impact Pressing of Ceramic Powders of a New Design

The paper investigates the influence of the configuration of an electromechanical pulse device of the electromagnetic-induction type (the thickness of the magnetic circuit and the position of the inductor) on the space-time characteristics of the device for impact pressing of ceramic powders of a new design. The tasks are solved using the numerical finite element method. It is shown at what combination of the thickness of the magnetic circuit and the position of the inductor the pulse of the electromagnetic force is equal to or exceeds the pulse of the electric induction force of recoil. Based on the results of the analysis of the graphs of the instantaneous values of the electromagnetic force and the force impulse as its integral indicator, a relationship was established between these indicators and the initial position of the inductor. The practicability of using the research results for the selection of rational design parameters of the device for impact pressing of ceramic powders and determination of the maximum values of its main electromechanical indicators has been established.
