破片模拟弹侵彻陶瓷/船用钢复合靶板的理论分析模型研究

摘要

Research development of ceramic/steel composite armor is reviewed. The process of 10g fragment simulating projectile (FSP) penetrating ceramic light-duty composite armor is divided into two phases, according to the absorption energy characteristics of ship steel and particularity of ceramic lightduty composite armor. Erosion deformation energy of FSP and hunch-dishing deformation of ship building steel are calculated. The hunch-dishing deformation absorption energy of ship building steel is divided into three parts: radial bending deformation energy, radial membrane stretching deformation energy and circumferential bending deformation energy. The calculating formulas of absorption energy are presented.The analytical model of ballistic limit velocity is built. The analytical results accord with experimental values, and also indicate that the erosion deformation energy of FSP and hunch-dishing deformation of ship building steel are the leading consumption energy mechanism.%简要回顾了陶瓷/金属复合靶板的研究现状.根据船用钢的吸能特点和船用陶瓷轻型复合装甲的特殊性,将10 g破片模拟弹侵彻陶瓷/船用钢的过程分为两个阶段,分别计算了破片模拟弹的侵蚀变形能和船用钢背板的隆起-碟型变形吸能,并将后者分为径向弯曲变形能、径向膜托伸变形能及周向弯曲变形能等,给出了各种能量的计算公式,建立了计算弹道极限的理论分析模型,其结果与实验吻合较好.结果表明,陶瓷/船用钢的耗能机制主要是弹体的侵蚀变形能和船用钢背板的变形能.
