摘要

为了探究具备抗多发弹打击的蜂窝点阵-陶瓷复合装甲在冲击波与破片联合载荷下的防护性能，改善当前防护装甲基于破片或爆炸冲击波单一载荷开展结构设计的不足，本文通过泡沫铝-弹丸复合弹模拟联合载荷，采用有限元模拟手段，研究了蜂窝点阵-陶瓷复合装甲在联合载荷作用下的结构动态响应与毁伤机理，明确了速度差和预变形两种协同作用机制。进一步，研究了联合载荷中爆炸冲击波与破片抵达先后顺序与抵达时间差对复合装甲防护性能的影响。最终，进行了参数化研究，讨论了蜂窝点阵-陶瓷复合装甲中，不同子结构关键几何参数对防护性能的影响规律，评估了不同子结构的防护贡献，为最优防护性能设计提供了指导。

Abstract

In order to investigate the protective performance of the ceramic composite armor subjected to combined blast and impact loading, and to improve the traditional armor design for fragments only or blast only, with numerical method, aluminum foam - fragment composite projectile was employed to explore the dynamic response and damage mechanism of honeycomb lattice enhanced ceramic composite armor under combined loading. Two synergistic mechanisms of pre-acceleration and pre-deformation were clarified. Furthermore, the effect of load arrival sequence and arrival time interval was studied. Finally, a parametric study was carried out to discuss the influence of key geometric parameters on the protection performance of the enhanced ceramic armor. The contribution of different substructures was evaluated to provide guidance for the optimal armor design.
