Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0034] The core component in the electromagnetic launch, the track 1 plays the role of conducting current and guiding the armature 2 and the projectile 3 during the launch of the electromagnetic railgun. In order to ensure the good contact of the circuit, the track 1 is in close contact with the armature 2. When launching, it is a high-speed sliding electrical contact process. The current amplitude flowing in the track 1 is very large, and the megaampere current makes the surface temperature of the track 1 very high. Therefore, what the track 1 adopts is a wear-resistant and ablation-resistant...

Abstract

The invention relates to an electromagnetic rail gun track, an armature and an electromagnetic rail gun, belongs to the technical field of electromagnetic rail guns, and solves the problem of serious ablation of the rail and the armature in the prior art. The guide surface of the track is provided with two evenly distributed curved surface protrusions, and the curved surface protrusions are arranged along the axis of the track; the cross-sectional shape of the curved surface protrusions perpendicular to the track axis is the same, and the ratio of the height of the cross-sectional shape to the chord length is 0.2‑ 0.3. The cross-sectional shape, cross-sectional size and position of the curved concave of the guide surface of the armature are matched with the curved convex of the guide surface of the track. The invention makes better use of the skin effect and proximity effect, so the current distribution in the track is relatively uniform, and the maximum current density value is small, which is beneficial to reduce the ablation phenomenon of the track surface and avoid the track burning at the corners. Severe erosion.

Description

technical field [0001] The invention relates to the technical field of electromagnetic guns, in particular to an electromagnetic rail gun rail, an armature and an electromagnetic rail gun. Background technique [0002] The working principle of the electromagnetic railgun is made according to the law of electromagnetic induction in physics. The two rails are parallel to each other, and the launch assembly slides along the axis of the rails. The word armature comes from a DC motor. Its function is to transmit the current between the two rails and accept the Lorentz force to push the projectile towards the muzzle for acceleration. , which converts electromagnetic energy into kinetic energy. [0003] Rails and armatures are the core components of electromagnetic launch. During the launch of electromagnetic railguns, rails play the role of conducting current and guiding armatures and projectiles. In order to ensure the good contact of the circuit, the track is in close contact ...
