【摘要】：为了研究CL-20基含铝炸药的爆炸反应机理,利用水中爆炸实验,测量了不同铝粉含量和粒度的CL-20炸药水中爆炸的冲击波参数、二次压力波参数,计算了冲击波能和气泡能。结果表明,水中爆炸的冲击波能和气泡能表征了爆轰和二次反应两个阶段的炸药爆炸能量分配,CL-20炸药中的铝粉主要在二次反应阶段发生反应,只有少部分的铝粉参与了早期的爆轰反应。气泡脉动形成的二次压力波能描述铝粉含量和粒度对二次反应过程的影响,铝粉含量对炸药的二次反应有显著的影响;铝粉粒度对炸药的水下爆炸的初始冲击波参数、冲击波能和气泡能的影响很小,对铝粉与爆轰产物的二次反应速率影响较大。
[Abstract]:In order to study the explosive reaction mechanism of CL-20 based aluminized explosives, the shock wave parameters and the two pressure wave parameters of CL-20 explosives with different aluminum content and particle size were measured by underwater explosion test, and the shock wave energy and bubble energy were calculated. The results show that the energy distribution of explosive explosion is characterized by the shock energy and the bubble energy in the two stages of detonation and the two reaction. The aluminum powder in the CL-20 explosive reaction occurs mainly in the two reaction stage, and only a small proportion of aluminum powder is involved in the early detonation reaction. The two bubble formation pressure wave can describe the effects of aluminum content and particle size of two times in the process of reaction, have significant effect of aluminum powder content two times in response to explosives; the initial impact of aluminum particle size of explosives by underwater explosion shock wave parameters, and can affect the bubble energy is very small, and the influence of aluminum powder two times the reaction rate of detonation products larger.
