Magnetic Pulse Complex for Attraction of Thin-Walled Metals with Resonant Charge of a Capacitive Energy Storage Device

The purpose of this work is to propose and substantiate the workability of a magnetic-pulse complex for attracting thin-walled metals, consisting of two successive circuits with a common capacitive energy storage device, the first of which is a resonant charger powered by an industrial voltage and frequency network, and the second unit is a discharge circuit with an inductor-tool for performing the assigned production task. When deriving the main analytical relationships for calculating the characteristics of the proposed resonant magnetic-pulse complex designed to attract sheet metals and operating as a resonant amplifier of the energy of an electric signal from an industrial voltage and frequency network, the mathematical apparatus of the theoretical foundations of electrical engineering and methods of integrating differential equations were used. The high efficiency of resonant formation of charge characteristics of a capacitive electric energy storage device from an industrial network of ~ 220 V at a frequency of ~ 50 Hz for ~ 0.1 s to a voltage of ~ 4595.85 V (gain is ~ 14.78 times) with a stored energy of ~ 2640 J (energy of the source ~ 8.47%, resonant energy ~ 91.53%) is shown. For a discharge circuit at a frequency of ~ 1500 Hz, it was obtained that the maximum energy in the inductor-tool is ~ 8.25 times higher than the energy consumed from an external power source. The discharge current in the inductor-tool is ~ 45270.4 A. With this current value there should be a sufficiently effective force impact on the workpiece.
