Hypotheses about the Electromagnetic Repulsion Mechanism and Simplification of the Equivalent Circuit Model

In this paper, mathematical modeling is served as a point of departure in order to radically achieve an optimal design of the electromagnetic repulsion mechanism (ERM). Firstly, we assumed that for the equivalent model of the metal plate, a metal plate-coil in series was equivalent to that in parallel, and that the mutual inductance between the two coils remained unchanged in the period of electromagnetic repulsion force exerting on the metal plate. Secondly, we obtained the mathematical expressions of a pulse current and an induced countercurrent. Lastly, the hypotheses and the mathematical expressions aforementioned were both validated according to comparisons between analysis and finite element simulations.
