摘要/Abstract

摘要： 采用实验研究和理论分析相结合的方法，对活性药型罩聚能装药破甲后效超压特性进行了研究。通过地面静爆实验，测试了活性药型罩聚能装药穿透不同厚度靶板后的内爆超压特性。结果表明，在给定活性药型罩聚能装药结构的条件下，内爆超压随穿靶厚度基本呈抛物线衰减规律。进一步结合准定常理想不可压缩流体力学理论，引入活性材料能量释放激活延时参数，建立了破甲后效超压半经验分析模型。利用该模型预测的活性射流破甲后效超压与实验测试结果吻合较好。分析了活性材料能量释放激活延时对破甲后效超压的影响特性。

Abstract: Armor penetration aftereffect overpressure produced by reactive material liner shaped charge is researched through experiments and theoretical analysis. Quasi-static explosion experiments are carried out to investigate the overpressure produced by reactive material liner shaped charge impacting the steel plates with different thicknesses. The result shows that the overpressure decays parabolically with the thickness of plate. Based on the quasi-steady incompressible Bernoulli equation, a model is developed to describe the armor penetration aftereffect overpressure by introducing the self-delay time of reactive materials. The results calculated by the proposed model show a good consistence with the experimental results. And the influence of the self-delay time of reactive materials on armor penetration aftereffect overpressure is analyzed.
