Description
technical field [0001] The invention belongs to the technical field of propellant and explosive laboratory test devices, and in particular relates to a friction load loading device, which is suitable for simulating the compression and impact load loading conditions of projectile charging during service. technical background [0002] The projectile body is filled with high-energy explosives. During service (penetration, armor-piercing, etc.), the explosives are subjected to inertial impacts, which may cause premature explosions, failing to reach the predetermined technical and tactical indicators. Therefore, the safety of explosives during the service of the charged projectile is one of the key issues concerned by the weapon development department. The reason for the premature detonation of explosives is generally recognized as a hotspot theory, and the ways of heat generation include impact, friction and so on. At present, the compression and impact loading conditions of th...
