The invention relates to the technical field of hypervelocity impact loading tests, in particular to a sabot separation device. The electromagnetic sabot separation device for a light-gas gun comprises an annular casing, annular electromagnets, a sensing device, a controller and an electric storage device, wherein a projectile and the sabot are accelerated by the light-gas gun to enter an electromagnetic separation device connected with a gun muzzle, and when the projectile and the sabot pass through the sensing device located on the inner wall of the electromagnetic separation device, the sensing device triggers the controller to control the electric storage device to produce strong current to power on the annular electromagnets and the annular electromagnets produce strong attraction force on the sabot made of a ferromagnetic high-polymer material. The sabot with a split structure is separated towards the lateral direction under the action of uneven electromagnetic attraction force,and meanwhile, after the sabot flies over the positions of the electromagnets, the annular electromagnets produce backward electromagnetic force on the sabot to slow down the sabot, so that the sabotand the projectile are separated. The sabot is separated from the projectile stably and smoothly without impact.
Description
technical field [0001] The invention relates to the technical field of ultra-high-speed impact loading tests, in particular to a bullet holder separation device. Background technique [0002] Researches on spacecraft protection, kinetic energy weapons, and high-pressure physics all require ultra-high-speed launch technology. Compared with other firing techniques, the light gas cannon is a particularly versatile device because it can fire a variety of projectile shapes, with a wide range of projectile masses, sizes and materials. Light gas gun is a device that uses light compressed gas to accelerate projectiles. There are first-level light gas guns, second-level light gas guns and third-level light gas guns. The first-level light gas gun can load larger mass projectiles to 0.5-2km / s, the second-level light gas gun can load the projectile with a smaller mass to 2-7km / s, and the third-level light gas gun can load the projectile to more than 10km / s. It can be used to simulate...
