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%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 JO9159 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.
