摘要
研究了小口径穿甲弹垂直撞击下双层陶瓷/金属复合靶板的优化计算,讨论了Florence模型的适用范围.给定靶板材料和子弹参数,由Florence模型导出靶板最小面密度及相应面板、背板厚度的计算公式.与现有试验数据比较表明,当面板厚度与弹体直径相当时,Florence模型与试验结果吻合较好;当面板厚度比弹体直径小得多时,计算结果偏低;当面板厚度比弹体直径大得多时,计算结果偏高,对于7.62 mm穿甲子弹,Florence模型精度较好,本文计算结果与试验结果吻合较好.
Optimization of two-layer ceramic/metal composite targets against ballistic impact by Armor Piercing Projectile（APP）was investigated. The application condition of Florence＇s model was discussed. Based on Florence＇s model, analytical formulas of minimum area density and the corresponding front and back plate thickness of the target were developed under the conditions that the APP and target materials were given. While the front plate thickness is approaching to the diameter of APP, the result of Florence＇s model coincide better with that of the tests. The calculation result is lower under the conditions that the thickness is much less than the diameter. While the thickness is much more than the diameter, the calculation result is higher. The accuracy of Florence＇s model is preferable, and the calculation result coincides with ballistic test data of 7.62 mm APP.
