Problems solved by technology
[0004] At present, the laboratory research on performance tests such as wear and ablation of rails is mainly based on simulation and material-level tests. It is impossible to test the performance of rails in service, and it is also difficult to provide test results for rail service performance. For engineering technology and manufacturing processes It is also difficult to make breakthroughs in the research on a series of problems such as low power efficiency, track wear, and armature planing that exist in the world, relying on simulation and material-level testing, thus restricting the improvement and breakthrough in the performance of rail guns

Embodiment approach
[0062] As an implementation, the test of the railgun includes the following steps:
[0063] Step 1, fix the guide rail in the guide rail groove of the fixing device, ensure that the two ends of the guide rail are in good contact with the corresponding conductive connectors at both ends of the fixing device, and put the armature 6 in the middle of the two parallel guide rails so that the bottom surface of the armature 6 is in contact with the base 9 Surface contact is realized, and both sides of the armature 6 are in surface contact with the guide rail;
[0064] Step 2, tighten the bolt 12 of the U-shaped clamping device 1 to ensure that the armature 6 of the guide rail is well connected, and adjust the resistance of the resistance box to determine the resistance of the external circuit;
[0065] Step 3, turn on the voltmeter at both ends of the capacitor, press the charging button, the voltage indication is the charging voltage of the capacitor;
[0066] Step 4, after the cha...

Description
technical field [0001] The invention relates to a test platform capable of testing the materials and properties of components such as rails and armatures of a rail-type electromagnetic gun. Background technique [0002] The orbital electromagnetic gun is made according to the law of electromagnetic induction. The two rails are parallel to each other. The launch assembly slides along the axis of the rail. kinetic energy. Among them, the rail and the armature are the core components of the rail gun. The rail plays the role of conducting current and guiding the armature and the projectile. In order to ensure good contact of the circuit, the rail and the armature need to be in close contact. [0003] During the launching process of the electromagnetic rail gun, the rail and the armature are in high-speed sliding electrical contact process, so the amplitude of the current flowing in the rail is very large, and the megaampere-level current makes the surface of the rail generate h...
