摘要

摘要: 采用火炮加载技术对HMX基JOB-9003炸药进行一维平面冲击实验。实验使用的飞片由蓝宝石和Kel-F黏合而成，撞击炸药后，先后传入两道不同压力的冲击波。通过组合式电磁粒子速度计测量撞击界面和炸药内部不同深度处的粒子速度，得到粒子速度-时间图。根据粒子速度-时间图，计算出撞击界面粒子速度和冲击波传播速度，进一步获得炸药雨贡纽关系。根据炸药雨贡纽关系，并对比已有实验数据，通过Pop图说明炸药在二次压缩下的“钝化”特性。

Abstract: One-dimensional plate impact experiments were performed to study the double shocks to detonation transition and Hugoniot state in the HMX-based explosive JOB-9003.The flyer was a combination of sapphire and Kel-F, which could pass two different pressure waves after the impact.We measured the particle velocities at the interface and the different depths using the Al-based electromagnetic particle velocity gauge technique, and obtained the particle velocity-time diagram, according to which we calculated the impact velocity, the shock wave velocity, and then the Hugoniot relation of the explosive.By comparing them with the existing experiment data in the Pop plot, we can draw the conclusion that the explosives pressed by the double shocks will exhibit desensitization features.
