摘要: 采用火炮加载技术对JOB-9003炸药进行一维平面冲击实验，利用组合式电磁粒子速度计记录了不同位置的粒子速度变化历程，获得了炸药的冲击Hugoniot线。利用实测的冲击Hugoniot线，对三项式状态方程进行标定，确定了JOB-9003炸药的JWL状态方程参数。Abstract: One-dimensional plane impact experiments with power gun were conducted on JOB-9003 explosives.The Hugoniot relation of unreacted JOB-9003 explosive was obtained by measuring the particle velocities at different depths with magnetic gauges.Moreover, the trinomial equation of state was calibrated with the experimental Hugoniot curve, and the JWL equation of state parameters of JOB-9003 explosive were determined.
