摘要

以Florence模型为基础提出了一种修正模型，可以用于求解金属/陶瓷复合装甲板的弹道极限速度。修正模型考虑到弹体在撞击过程中的变形，在原始Florence模型基础上，结合泰勒理论来计算弹体变形能。修正方程的理论解与Winkins的实验值较为吻合。最后根据修正的Florence模型，分析了板厚参数对靶板弹道极限速度的影响。

Abstract：In this paper based on the Florence model, a modified model has been presented for penetration of deformable projectiles into ceramic-metal targets.By considering flattening of projectile，the deformation energy could be calculated by modified Taylor theory.The ballistic limit velocity of projectile predicted by new analytical model has a good agreement with the experimental results.Based on the Florence's model, the influence of the plate thickness on ballistic limit velocity was analyzed.

Key words： florence model ceramic/metal armor numerical simulation penetration ballistic limit
