摘　　要：为增强聚能战斗部的后效毁伤能力,设计一种金属药型罩与PTFE/Al反应材料相结合的后效毁伤聚能战斗部,并通过数值仿真进行改进与分析;开展后效毁伤战斗部静爆试验,并结合数值仿真对含能毁伤元的成型、侵彻和后效作用过程进行研究。研究结果表明:通过加装挡环可以有效调整PTFE/Al在成型过程中的位置,使其位于惰性弹丸之后;相较于单一惰性药型罩聚能装药,在原有破甲能力基础上,破甲后的空气冲击波强度明显增强,后效毁伤能力提升显著;反应材料在靶板内的反应扩孔作用是削弱后效冲击波强度的主要原因,适当提高反应材料的反应阈值可增强后效冲击波强度;综合分析影响毁伤性能的因素,认为半Cu罩结构的毁伤效果更好。研究成果可为增强聚能战斗部后效毁伤能力的设计提供重要参考与数据支撑。To enhance the aftereffect damage capability of shaped charge warhead,the aftereffect damage shaped charge warhead combining metal liner with PTFE/Al reaction material is designed,and it is improved and analyzed by numerical simulation.The static explosion test of aftereffect damage warhead is carried out,combined with numerical simulation,the forming,penetration and aftereffect of energetic damage element are studied.The research results show that:the position of PTFE/Al in the molding process can be effectively adjusted by adding retaining ring,so that it is behind the inert projectile;Compared with a single inert liner shaped charge,on the basis of the original armor-piercing ability,the intensity of air shock wave after armor-piercing is obviously enhanced,after-effect damage ability is improved significantly;The reactive reaming of reactive materials in the target is the main reason for the weakening of shock wave intensity,and increasing the reaction threshold of reactive materials can enhance the shock wave intensity;The factors affecting the damage performance are analyzed comprehensively,and it is concluded that the damage effect of small diameter Cu liner structure is better.The research results can provide important reference and data support for the design of enhancing the aftereffect damage capability of shaped charge warhead.
