摘要/Abstract

摘要： 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（3.43 J）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。

Abstract: The responses of high-density HMX-based and PETN-based explosives to electrostatic discharge(ESD) are tested by JGY-50 electrostatic spark tester. Two discharge modes including impenetrating discharge and surface discharge are employed to simulate the different ESD scenarios. The results show that the response of high-density explosives include heat and shock effects. The heat effect of PETN-based explosive and the shock effect of HMX-based explosive dominate under ESDs. No detonation is probably observed because there is less accessible surface area and low permeability of high-density solid explosive allowing little convective burning, and the energy of ESD can not be coupled effectively to high-density solid explosives.

Key words: ordnance science and technology, electrostatic discharge, explosive, heat effect
