【摘要】 讨论了初级飞片撞击起爆炸药块,使之发生强爆轰并驱动次级飞片达到高速度的理论问题。解析分析表明,初级飞片作用下炸药块中形成强爆轰逐渐衰减成为正常爆轰,波后产物具有较宽的压力平台,可以有效地使次级飞片加速到6～7km/s,再经过阻抗匹配的组合飞片增速,得到10km/s以上速度的完整末级飞片。这种装置结构简单,操作简便,成本较低,作为高速碰撞和动高压加载的撞击器,具有重要的应用前景。更多还原

【Abstract】 The problem of accelerating metallic flyers to ultra high speed with strong detonating explosive slabs has been analyzed and numerically simulated in the paper, where the next stage explosive slab is impacted by the flyer of previous stage and accelerates the another next stage flyer to a higher speed. There is a high plateau in the detonation products pressure profile of the slab, to which the effective acceleration is attributed. A combination of impedance matched flyers of the final stage is impacted by the strong detonating explosive driven flyer at speed 6-7 km/s, and could be sped up over 10 km/s. This kind of high speed impactors have the advantages of simple structure, lower cost, smart design and promising in many applications of high dynamic pressure loading and high velocity impact.更多还原
