Abstract

The invention discloses an assembled metal solid armature for electromagnetic emission and a manufacturing method thereof. The composite metal solid armature is composed of similarly shaped pure copper block (3), pure aluminum block (2) and industrial pure titanium block (1) according to the ratio of the contact area with the electromagnetic emission track of 1:2:1.3 and conduction Arrangement order from small to large, through duralumin double dovetail groove connection keys I, II (4, 4') interference fit combined into one, the metal solid armature of the combination is a C-type armature. The invention adopts the segmented combination technology to skillfully realize the gradient distribution of electrical conductivity, and overcome the problem that it is difficult to realize the gradient change of electrical conductivity with a single material or the problem that it is difficult to prepare the gradient change of electrical conductivity. Since the conductivity gradually decreases and the strength increases from the front section to the back section, it is beneficial to realize the redistribution of current, weaken the phenomenon of being too concentrated in a single tail, and improve the anti-ablation ability and anti-electromagnetic force ability of the solid armature.

Description

technical field [0001] The invention relates to a combined metal solid armature for electromagnetic emission and a manufacturing method thereof, which belongs to the technical field of electrical contact materials. Background technique [0002] The solid armature is the key component in the electromagnetic launch device, and it is the carrier of electric current and electromagnetic force. When the pulse current flows through the solid armature, the solid armature is subject to complex physical coupling processes such as electricity, magnetism, heat, and stress, while the current and Joule heat are often concentrated at the tail of the armature and the track contact. Due to the strongly uneven distribution of electricity, magnetism, force, and heat on the solid armature, it often causes strong ablation and fragmentation of the solid armature, which in turn affects the emission efficiency of the solid armature. Aiming at the current skin effect, uneven heat and force distribu...
