含铝炸药冲击波感度的实验和数值计算研究

炸药的冲击波感度是选择武器装药的重要指标,为了比较分析新研含铝炸药的冲击波感度,通过大隔板实验和入射冲击波压力剖面的数值计算,研究了两种带金属外套的新研含铝炸药HL-10-L-1和HL-109-L-1在长脉冲低压幅值冲击波作用下的引发行为,给出了这两种炸药不发生爆轰反应和不发生强烈反应的边界隔板厚度和∫p2dt边界,分析认为采用∫p2dt值来推断评估炸药在低幅值压力脉冲作用下所发生的反应情况比临界隔板厚度更加合理。

Experimental and Numerical Calculation Study on Shock Sensitivity of Aluminum Explosive

In order to compare and analyze the shock wave sensitivity of a new aluminum explosive, the initiation behavior of two aluminum explosives (HL-10-L-1 and HL-109-L-1) under long period and low value impulse loading were studied using big gap test and numerical calculation. The critical gap thickness and ∫p~2dt of nondetonation and nonviolence reaction were obtained. Analysis shows that adopting ∫p~2dt value to infer the reaction behavior of explosive under low value pressure pulse is more reasonable than the critical gap thickness.
