Embodiment 1

[0032] Such as figure 1 As shown, this embodiment provides a method for controlling the rate of fire of a miniature reluctance coil cannon projectile based on switching timing, including the following steps:

[0033] 1) Electromagnetic field modeling for reluctance coilgun

[0034] The reluctance coilgun model includes four parts: a ferromagnetic projectile 1, a multi-turn coil 2, a projectile motion domain 3 and a solution domain 4, wherein the diameter of the projectile motion domain 3 is larger than the outer diameter of the ferromagnetic projectile 1, The multi-turn coil 2 is sleeved on the outer circumference of the ferromagnetic projectile 1 and the projectile motion domain 3, and the diameter of the solution domain 4 is greater than the outer diameter of the multi-turn coil 2;

[0035] 2) Electromagnetic field finite element analysis of reluctance coilgun

[0036] Set the finite element analysis solution mode to transient, and connect the external circuit as the excit...

Abstract

The invention relates to the technical field of electromagnetic emission, in particular to a micro reluctance coilgun projectile firing rate control method based on a switching sequence. A motion state curve of projectiles in a coil magnetic field is obtained through finite element analysis of electromagnetic emission, the projectile speed corresponding to each time point is obtained through the motion state curve, a control pulse is output by a single chip microcomputer to control a fully controlled switching device, so that a transmission circuit is controlled to be connected or disconnected, the purpose of controlling generation and disappearance of a coil magnetic field is achieved, motion time of the projectiles in the coil magnetic field is controlled, and the purpose of controllingthe projectile outlet speed is achieved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic launch, in particular to a method for controlling the rate of fire of a miniature reluctance coil cannon projectile based on switching timing. Background technique [0002] Electromagnetic emission technology is a new concept kinetic energy emission technology that emerged after chemical energy emission. According to the difference in structure and principle, it can be divided into two types: electromagnetic track type and electromagnetic coil type. The former can be understood as a single-turn linear motor, and the latter can be understood as a cylindrical motor, which essentially works according to the principle of the motor. Electromagnetic emission technology has been around since 1845, British physicist Charles. Since Wheatstone designed the first reluctance linear motor based on electromagnetic emission, after more than a century of development, electromagnetic emission technology h...
