摘　　要：为了研究弹体以低于400m·s^(-1)的侵彻速度侵彻陶瓷-混凝土复合靶体时,侵彻深度与侵彻速度及材料参数之间的关系,利用Forrestal空腔膨胀理论和弹体侵彻混凝土靶体的经验公式,在弹体对靶体的不同侵彻状态下,计算了弹体受到的侵彻阻力。依据牛顿第二运动定律,建立了弹体低速撞击陶瓷-混凝土靶体的侵彻深度计算模型,并将理论计算的侵彻深度与已有试验数据进行了比对分析,结果表明两者间的相对偏差较小,证明了该理论计算模型及其计算结果具有可靠性。The relationships among the penetration depth, the penetration velocity, and the material parameters are studied when the projectile penetrates into ceramic concrete composite targets at a speed below 400 m ·s -1 . By using the Forrestal’s cavity expansion theory and the empirical formula of the concrete target, the penetration resistance of the target subjected to a projectile is calculated. Based on Newton’s second law of motion, a calculation model for calculating the penetration depth of a projectile into a ceramic concrete target is established. Compared the penetration depth calculated by the calculation model with the experimental data, it is found that the deviation between them is small, which proves the reliability of the calculation model.
