摘要

摘要: 利用粒子速度对比法实验技术，通过电磁粒子速度计测量了PMMA飞片同时撞击PMMA样品与待测炸药样品界面的粒子速度u1和u2，获得了未反应JOB-9003炸药的冲击Hugoniot关系；利用叠加原理和疏松材料冲击绝热线的计算方法，对未反应炸药的冲击绝热线进行了计算。计算结果与实验数据符合较好。

Abstract: The Hugoniot relation of unreacted JOB-9003 explosive was investigated experimentally by using Particle Velocity Matching Method. The PMMA flyer is driven by detonation wave which is attenuated with a thick plate. Magnetic gauges were used to respectively record the interface particle velocity u1 between the PMMA flyer and the explosive sample as well as u2 between the PMMA flyer and PMMA sample. Furthermore, considering unreacted explosives as composite and porous materials, the shock Hugoniot relation of JOB-9003 explosives are calculated by using Hugoniot calculation method for porous material, as the known shock Hugoniot of each component. The calculated results are in good agreement with the experimental data.
