摘要

摘要: 研究了刚性卵形弹正撞击下金属厚靶的侵彻与贯穿性能。基于局部化破坏的假设，认为弹体在侵彻过程中，弹表面受到的法向阻力由材料弹塑性变形引起的静阻力和与瞬时侵彻速度有关的动阻力两部分组成，是侵彻速度的线性函数。根据弹头长度和靶厚的相对大小，建立了二阶段的靶体侵彻模型和三阶段的靶体贯穿模型。对于固支金属厚靶的贯穿，给出了厚靶贯穿模型的适用范围。比较发现，模型预测和实验数据在侵彻深度、弹道极限和残余速度方面吻合得较好。

Abstract: An analytical investigation into the penetration and perforation of thick metal targets struck normally by rigid ogival-nosed projectiles over a wide range of velocities was conducted. Based on the assumption that the deformation is localized and that the mean pressure offered by the target materials to resist the projectiles is no longer a constant but a linear function of penetration velocity, equations are derived for predicting the depth of penetration in the targets and the ballistic limits or residual velocity in the case of perforation. Furthermore, the range of applicability of the perforation model is discussed. It transpires that the present model predictions are in good agreement with the test data for thick metallic targets in terms of penetration depth, residual velocity and ballistic limits.
