Abstract:

In order to improve the breaking speed of the rapid repulsion mechanism and meet the requirements of demagnetization switch applications, the finite element method is used to establish a two-dimensional axisymmetric model of the rapid repulsion mechanism with Maxwell electromagnetic simulation software according to the dynamic characteristics requirements of the demagnetization switch for the rapid repulsion mechanism. The effects of the thickness, radius, material, spacing, coil turns, capacitance, and voltage of the repulsive disk on the dynamic characteristics of the rapid repulsion mechanism are analyzed through simulation. The results show that the optimizing relevant parameters can improve the dynamic characteristics of the fast repulsion mechanism, and the simulation results provide guidance for the prototype design of the fast repulsion mechanism.
