摘　　要：采用平面波发生器爆炸驱动不同厚度的飞片撞击带隔板装药,获得了某新型炸药与THAL炸药的冲击波起爆临界隔板厚度。基于一维冲击波传播理论,建立了炸药临界起爆特性参数分析模型,并利用所测的两种炸药冲击波起爆临界隔板厚度,结合炸药及隔板材料的冲击Hugoniot参数测试结果,计算得到了两种炸药的冲击波临界起爆压力和起爆能量常数。Using plane wave generator to drive flying plates with different thickness to impact the charge with baffle, the critical initiation baffle thickness for both a new explosive and the THAL explosive are obtained. Based on the theory of one dimension shock wave propagation, a theoretical model calculating critical shock initiation characteristic parameters of explosive is presented. And by combining the critical initiation baffle thickness and shock Hugoniot parameters for two explosives and baffle material, the critical initiation pressure and initiation energy for both explosives are obtained.
