弹丸高速/超高速撞击陶瓷/金属复合靶的数值模拟

Numerical Simulation of Projectile Hit the Ceramic / Metal Composite Target

陶瓷/金属复合装甲是新型的热门装甲,将韧性材料和高硬度的脆性材料结合到一起,具有良好的抗弹和防护效果,在轻型装甲车辆、舰、坦克、直升机中具有良好的应用前景。本文通过光滑粒子流体动力学(SPH)方法模拟弹体高速撞击陶瓷/金属复合靶,研究弹速300~2000 m/s的抗侵彻和弹速3000~8000 m/s的碎片云特性,并与工况对比,通过改变陶瓷/金属厚度比、弹丸直径等参数,分析了其对靶板高速撞击特性的影响。

Ceramic / metal composite armor is the new hot armor,the toughness of the material and high hardness brittle materials bonded together,with good anti-bomb and the protective effect,there is in light armored vehicles,ships,tanks,helicopters,spacecraft,satellites good application. Therefore,research has important implications for projectile ceramic / metal composite target impact. By Autodyne different shapes projectile at extremely high speeds at different speeds hit the ceramic / metal composite target,metal target,when the target of destruction ceramic target to simulate the theoretical analysis is given of ceramic / metal composite armor excellent mechanical causes of protective properties.
