轻型陶瓷/金属复合装甲抗弹分析模型研究

An Analytical Model of Ballistic Impact on Light Ceramic/Metal Lightweight Armours

为探讨轻型陶瓷复合装甲结构设计,在弹道冲击响应特性试验研究与分析的基础上,针对薄金属背板支撑的陶瓷复合装甲,以金属背板发生碟型变形—剪切—花瓣型失效为分析对象,建立了陶瓷/金属复合装甲侵彻过程的近似解析模型。模型考虑了弹体的侵蚀失效及陶瓷碎片脱离弹头表面,向侧向和反冲击方向的运动,得到了陶瓷/金属复合装甲中金属背板的动态冲击响应及失效,陶瓷/金属复合装甲的弹道极限速度计算公式和弹体的剩余速度计算方法,模型分析结果与试验结果吻合良好。

To explore the design method of light ceramic composite armor, an approximate analytical model of ballistic impact on ceramic/metal composite armor focused on thin back plate and dishing shearing-petal failure is proposed, based on response characteristics experimental investigation and analysis of the response characteristics. The model takes the projectile＇s erosion failure and ceramic fragments out of bullet surface into account, moving in the direction of lateral and the anti-impacting to get the dynamic impacting response and failure in the ceramic/metal composite armor metal back panel and formula of ballistic limit velocity of the ceramic/metal composite armor and calculation. Model analysis results are in good agreement with those obtained with the test results.
