摘要
长杆体撞击平面夹层炸药时 ,冲击波直接起爆的现象比较普遍 .但如果撞击速度低于冲击起爆临界速度时 ,夹层炸药背板表面的反射波对起爆的影响也不可忽略 .建立了平面夹层炸药反射冲击起爆模型 ,分析了杆体直径、盖板厚度以及炸药厚度与反射波冲击起爆炸药的关系 .研究结果表明 。
Generally sandwich explosive is initiated by the shock produced by impact of the projectile. But if the impact velocity is lower than critical initiation velocity, the reflected-shock on the surface of back plate may initiate the explosive. The model of reflected-shock imitiation of sandwich explosive is established. Diameter of projectile?thickness of the front plate and thickness of explosive layer have certain influence on reflected-shock initiation. The result shows that reflected-shock has some distinct effects on initiation when the velocity is lower than direct shock initiation thresholds.
