Research On The Damage Effect Of Ceramic Armor Piercing

Armor-piercing bombs rely on their own kinetic energy to penetrate and destroy armored target ammunition,which alternates with armored targets.In this paper,an armor-piercing projectile with a ceramic warhead is used to penetrate a ceramic composite target plate and a“hard-to-hard” method is used to improve the damage effect on the target of the ceramic composite armor.A 30 mm sub-aperture trailing stable shelling ceramic penetrator is designed..Firstly,the penetrating arm damage characteristics and the penetration mechanism were analyzed using the armor-piercing mechanics theory;then,the structural design and optimization of the 30 mm-diameter caliber stable shelling ceramic penetrator were performed and the strength was checked;14.5 mm ceramic projectiles and standard bombs were established.The numerical model uses TG and LS-DYNA to numerically simulate its penetration process.Through two sets of comparative simulations,a more reasonable structure is selected;then,with the selected structure,14.5mm ceramic projectiles and standard bombs penetrate the ceramic.The composite targets were studied for damage experiments.The experimental results show that the penetration effect of ceramic projectiles is better than that of standard bombs;the mathematical model of ceramic penetrators is established,and the method of controlling variables is used in the core structure,ceramic head structure,and different speeds.Different target angles and other factors were used to simulate the damage effect of ceramic composite armor.The structural scheme was compared and the advantages and disadvantages were comprehensively analyzed.A relatively reasonable scheme was selected for exploration to provide a new approach for improving the damage of ceramic composite target.In the experimental comparison of the 14.5mm ceramic projectile and the standard projectile penetrating the ceramic composite target plate,when the ceramic projectile penetrates the ceramic surface target,the opening crater is larger,and the damage effect to the back target is obviously stronger than that of the standard projectile.As a result,the ability of the projectile to penetrate the ceramic composite target is improved.In the simulation of the subaperture trailing stable shelled ceramic penetrator,it is concluded that the muzzle velocityand the target angle have a great influence on the damage effect.Under the premise of the initial velocity of the ceramic pierced projectile,the larger the target angle is,the smaller the damage of the ceramic piercing projectile is.Under the premise that both the initial speed and the target angle are determined,the damage effect on the target depends on the core structure of the core.It provides theoretical guidance for the development of larger-caliber ceramic penetrators.
