Abstract:

?为研究成型炸药在静电放电作用下的响应特性,采用JGY-50静电火花感度仪,建立了可模拟击穿放电和表面放电两种放电情形的实验装置,对两种较为典型的奥克托今(HMX)基和太安(PETN)基炸药片进行了实验研究。研究发现:炸药片对静电的响应主要是热效应和冲击效应相互作用的结果。对于实验中偏脆性的HMX基炸药,静电的冲击作用效应较为明显。而对于实验中偏塑性的PETN基炸药,静电的热作用效应更为明显。在较高静电放电能量(3.43J)作用下两种炸药片均未发生爆炸反应。分析认为这主要是由于成型炸药密度较高,且渗透性低,不利于静电放电能量的耦合以及反应后形成对流燃烧,致使反应无法自持而最终熄灭。
