摘　　要：蜂窝夹层结构因对子弹和各类爆炸物具有较好的防护效果而作为一种潜在的装甲结构被越来越多地应用于军用车辆和舰船。通常蜂窝夹层结构在战场环境下会受到子弹和爆炸物等不同形式的高速冲击,并且这些冲击会导致蜂窝夹层结构产生不同形式的损伤,因此当前国内外学者对蜂窝夹层结构抗高速冲击性能及其损伤模式进行了大量研究。本文分别对国内外爆炸冲击和弹道冲击两种不同形式的高速冲击研究进行回顾和总结。在爆炸冲击方面,分别从空爆试验、水下爆炸试验、流固耦合效应和芯层形式差异等方面进行论述。在弹道冲击方面,分别对弹道冲击试验、蜂窝夹层结构等效建模、面板的损伤形式以及弹道极限速度等方面进行论述。并在最后对当前蜂窝夹层结构高速冲击试验及仿真中存在的不足及其改进方法进行论述。Honeycomb sandwich structure is more and more used in military vehicles and ships as a potential armor structure because of its good protection effect against bullets and various explosives.Generally,honeycomb sandwich structures will be subjected to different forms of high-speed impact such as bullets and explosives in the battlefield environment,and these impacts will cause different forms of damage to honeycomb sandwich structures.Therefore,scholars at home and abroad have conducted a lot of research on the anti-high-speed impact performance and damage mode of honeycomb sandwich structures.This paper reviews and summarizes the domestic and foreign research on two different forms of high speed impact,namely,explosion impact and ballistic impact.In terms of explosion impact,it discusses the air blast test,underwater explosion test,fluid-structure coupling effect and core form difference,and in terms of ballistic impact,it discusses the air gun test,equivalent modeling of honeycomb sandwich structure,damage form of panel and ballistic limit velocity.Finally,this paper discusses the shortcomings and improvement methods in the current high-speed impact test and simulation of honeycomb sandwich structures.
