摘　　要：高能炸药是各类武器弹药毁伤的能量之源。研究高能炸药(凝聚相炸药)的损伤和点火特性对武器弹药的安全性具有重要意义。从成型工艺、损伤实验模拟、损伤的观测与表征、损伤与点火相关性等4个方面介绍了凝聚相炸药损伤-点火特性的研究进展。首先,探讨了压装、浇注、熔铸等成型工艺对装药初始损伤的影响;其次,对凝聚相炸药在使用过程中损伤的产生、实验模拟和观测与表征方法进行总结;针对典型损伤类型分析了炸药的损伤-热点-点火过程;最后,基于研究现状分析,提出凝聚相炸药损伤-点火特性研究未来的发展趋势和面临的挑战。High energy explosives are the source of energy for the destruction of various weapons and ammunition.Study on the damage and ignition characteristics of high-energy explosives(condensed phase explosives)is of great significance for the safety of weapons and ammunition.The research progress on the damage and ignition characteristics of condensed phase explosives was introduced from four aspects:molding process,experimental simulation of damage,observation and characterization of damage,and damage-ignition correlation.Firstly,the influence of molding processes such as press-fitting,pouring,and melting and casting on the initial damage of the charge was explored.Secondly,the generation of damage,experimental simulation,observation and characterization methods of damage during the use of condensed phase explosives were summarized.Furthermore,the damage-hot spot-ignition process of explosives was analyzed in terms of the typical types of damage.Finally,based on the analysis of the current research status,the future development trends and challenges of damage-ignition characteristics of condensed phase explosives were proposed.
