摘要: 采用双灵敏度激光速度干涉仪(VISAR)测量了JOB-9003和JB-9014两种炸药平面一维爆轰驱动飞片的速度历史，比较了二者的做功能力；并用DYNA2D程序进行了数值模拟。在有JO-9159炸药的条件下，实验和计算结果表明，JB-9014炸药的做功能力可以达到JOB-9003炸药的75.0%；无JO-9159炸药条件下的计算结果表明，JB-9014炸药的做功能力约为JOB-9003炸药的71.2%

Abstract: A double-sensitivity VISAR was used to measure flyer velocity driven by JB-9014 and JOB-9003 explosives to compare their ability of acceleration. Numerical simulation was performed with the finite element hydrocode DYNA2D. Experimental and calculated results with JO-9159 explosive show that relative kinetic energy of flyer driven by JB-9014 may reach 75.0% of that driven by JOB-9003. Calculated results without JO-9159 explosive show that relative kinetic energy of flyer driven by JB-9014 may reach 71.2% of that driven by JOB-9003.
