摘要

摘要: 为研究以HMX为基的固体高能炸药的燃烧转爆轰性能，采用同轴电探针和压力传感器测试技术对常用的A、B两种压装高密度高能炸药开展燃烧转爆轰实验，研究装药组分和约束条件对压装高密度炸药燃烧转爆轰性能的影响。实验结果表明：这两种压装高密度炸药难以发生燃烧转爆轰；在强约束条件下（45号钢，内径25.4 mm、外径65 mm、长度600 mm），A压装炸药（HMX质量分数为95%，密度为1.86 g/cm3）基本实现了燃烧转爆轰，爆轰诱导距离约为545 mm；在相同的实验条件下，A压装炸药比B压装炸药（HMX质量分数为87%，密度为1.84 g/cm3）更易于发生燃烧转爆轰，即A压装炸药的安定性相对较差。

Abstract: This paper deals with the experimental findings of the characteristic of deflagration-to-detonation transition in two kinds of pressed explosivesA and B. A series of tests are performed on the high-density explosives. Electrical pins and pressure sensors are used to measure the pressures and velocities of shock, flame, or detonation wave. The experimental results show that it's very difficult to obtain the transition in the pressed explosives. The phenomenon of low velocity detonation (LVD) is achieved under the confinement condition that the length of DDT tube is 400 mm. A deflagration-to-detonation transition in the pressed explosives of A is obtained under the stronger confinement condition that the length of DDT tube is 600 mm and the detonation-induced distance is slightly longer than 545 mm. It's also concluded that the pressed explosive of A is more sensitive to transit into detonation than the pressed explosive of B under the same experimental conditions.
