摘　　要：叠层复合装药是由两种或两种以上装药通过叠加的方式复合而成,可以通过装药结构设计调控其安全性和能量输出特性。为研究叠层复合装药的殉爆安全性,选取典型高能炸药与钝感炸药组合的叠层复合装药为研究对象,通过数值模拟和殉爆试验研究装药结构对临界殉爆距离的影响规律。结果表明,相比于单一高能炸药PBX‑1,复合装药临界殉爆距离可减小53.3%(由7.5 mm减小至3.5 mm),能量降低22.9%;复合装药中钝感炸药厚度必须要达到特定阈值(3 mm)以上才能明显降低复合装药临界殉爆距离;随着钝感炸药占比增大,复合装药临界殉爆距离趋近于单一钝感炸药PBX‑2的临界殉爆距离。Laminated composite charge is composed of two or more different charges by way of superposition,in which the safety and power performance can be regulated through the design of charge structure.To study the sympathetic detonation safety of laminated composite charge,typical composite charges which contain both the high energy charge and insensitive charge were selected as research objects.The effect of different charges structure on critical sympathetic detonation distance was explored through numerical simulation and sympathetic detonation tests.Results showed that,compared to simple high energy charge,the sympathetic detonation of composite charge decreases 53.3%(from 7.5 mm decreases to 3.5 mm),while energy decreases 22.9%.The thickness of insensitive charge must reach a certain threshold(3 mm)in order to reduce the critical sympathetic detonation distance obviously.As the content of insensitive charge increases,the critical sympathetic detonation distance is closer to insensitive charge.
