用组合式电磁粒子速度计研究一种活性材料的反应特性
|
摘要
针对一种密度为5.2g/cm~3的活性材料,用57mm口径火药炮发射飞片撞击活性材料产生平面冲击波的加载方式,首次采用组合式电磁粒子速度计测量了活性材料的粒子速度历程,同时获得了活性材料内部冲击波的传播轨迹。研究表明,在高速飞片撞击情况下活性材料可以发生反应,但是反应速率较慢,释能过程较长,反应无法自持。将活性材料与PBX 9502炸药以及惰性材料的粒子速度历程进行对比发现,活性材料的反应发展过程介于炸药与惰性材料之间。该研究方法可以用于研究其他活性材料反应特性,相应的研究结果可以为活性破片战斗部的活性材料选择以及活性破片设计提供参考。
A reactive material with the density of 5.2g/cm~3 was impacted by high velocity flyers launched by a φ57 mm powder gun and,for the first time in research,its particle velocities and shock wave histories were measured with embedded electromagnetic particle velocity gauges.The results indicated that,though the reactive material could be initiated when impacted by high velocity flyers,its reaction rate was slow and its energy release process lasted for a long time,the reaction is not self-sustained.By comparing the particle velocities of the reactive material with those of PBX 9502 and the inert material,we found that the reaction characteristics of the reactive material can be defined as somewhere between those of PBX 9502 and the inert material.This method can be applied to researches on the reaction characteristics of other reactive materials,and the corresponding experimental results provide reference to the materials choice and reactive fragments design for reactive fragment warheads.
