摘　　要：抗爆容器在内部炸药爆炸作用下的研究与应用是涉及含能材料、爆炸与冲击动力学、振动力学的多学科交叉问题。抗爆容器的内部爆炸效应与动态力学行为研究是提升装备抗爆性能的重要基础,其中的应变增长、反直观等行为与机理是具有重要科学价值的研究问题。本研究从抗爆容器的内部爆炸载荷特性与效应、金属抗爆容器的动力学响应机理、抗爆容器的复杂工况、温压炸药和破片战斗部的爆炸效应、复合材料抗爆容器等五个方面综述了相关研究进展和关键科学发现。分析指出只有在建立有效的力学分析模型和充分揭示结构动力学响应机理的基础上,才能有效指导复杂工况下的爆炸毁伤效应评估和防护结构分析设计。针对高能毁伤炸药和高性能防护材料带来的挑战和机遇,提出了爆炸毁伤与安全防护研究的重要方向和发展趋势。The study and application of explosion containment vessels(ECVs)subjected to internal blast loading is a multidisci⁃plinary and interdisciplinary issue encompassing energetic materials,explosion and impact dynamics,and vibration mechanics.The investigation on the internal blast effects and dynamic mechanical behavior of ECVs is an important foundation for enhanc⁃ing the explosion⁃resistant performance of equipments,and the mechanisms of strain growth and anti⁃intuitive phenomenon are important scientific issues.The relevant research progress and key scientific findings are reviewed from five aspects:the internal blast loading characteristics and effects within ECVs,the dynamic response mechanisms of metal ECVs,the complex working conditions of ECVs,the blast effects of thermobaric explosives and fragmentation warheads,as well as composite ECVs.The analysis demonstrates that establishing an effective mechanical analysis model and fully revealing the dynamic response mecha⁃nisms of structures can effectively guide blast damage assessment and protective structures’analysis and design under complex working conditions.Considering the challenges and opportunities posed by high destructive explosives and high⁃performance protective materials,this study proposes the fundamental directions and emerging trends in the study of blast damage and safety protection.
