Structure Design And Power Simulation Of Energetic Core Small Caliber Shelled Armour Piercing Projectile

The terminal defense is a self-defense defense in response to an incoming missile approaching,so terminal defense is very important.In order to improve the terminal d efense technology,make up for the lack of damage caused by the lack of kinetic ener gy of the traditional inert armor-piercing projectile,the lack of kinetic energy of ordin ary fragments,and the insufficient number of anti-missile missile launches and the low hit rate.This paper is based on the penetration of 30 mm armor-piercing projectiles.T he characteristics of the target plate The structural design of the energetic shelling arm or-piercing projectile is equipped with the gun to launch the "barrage",so that each armor-piercing projectile is equivalent to energetic fragments,increasing its damage effi ciency,maximizing the damage efficiency,and improving the end defense technology.The thesis uses a combination of theoretical analysis and numerical simulation to study the structural design and damage efficiency of the energetic shelling armor-pierci ng projectile.First study the detonation threshold of energetic materials,and then anal yze the target vulnerability of the "Tomahawk" cruise missile,establish an equivalent s imulation target,and then carry out the energetic loading based on the near-anti-cann on projectile of the ultra-high-rate weapon Material shelling and armor-piercing projecti le structure design.Put the designed structure on the LS-DYNA platform to simulate t he penetration process of the energetic shelling armor-piercing projectile,obtain the fai lure time of the energetic material of the equivalent simulated target of the missile pe netrating the missile and the optimal speed at the failure location,and then at the opti mal speed The power of the energetic material to enhance the shelling armor-piercing projectile under working conditions verifies that the design of the armor-piercingproject ile in this paper is reasonable.The results show that the energetic shelling armor-pierc ing projectile increases the hot spot damage on the basis of the kinetic energy damage.The superposition of the two damage modes has significantly improved the d amage efficiency of the terminal interception,and greatly increased the damage power.According to the research in this article,the conclusions and research methods ob tained can be used as a reference basis for ammunition to enhance the damage power of the warhead to improve the short-range anti-missile capability.
