摘　　要：为了获得高速破片撞击下钝感装药的安全性响应规律及传爆药非理想起爆对该过程的影响,采用高速破片撞击试验方法,对TATB基PBX装药(PBX-C04)和PBX-C04/HNS复合装药结构进行了试验研究。基于超压测试、鉴证板破坏情况和残药的理化分析,分析了撞击速度、传爆药非理想起爆及高温对PBX-C04钝感主装药高速破片撞击安全性的影响。结果表明,常温下PBX-C04主装药具有优异的高速撞击安全性,1970 m·s^(-1)的高速破片撞击下仅发生燃烧反应,引入六硝基茋(HNS)传爆药后,相同撞击速度下PBX-C04主装药反应烈度提高为爆燃反应。复合装药结构加热至200℃时,1640 m·s^(-1)撞击速度下,复合装药结构发生了爆轰反应,证明高温可急剧恶化复合装药结构的高速撞击安全性。Ammunitions might experience safety threats of high-temperature heating,high-speed fragment impact,and their com-bined effects in battlefield.In order to investigate the reaction phenomenon of insensitive explosive PBX-C04 under high-speed impact and the effects of high-temperature and booster charge on this reaction phenomenon,the insensitive explosive safety experiments under high-speed fragment impact were carried out,and the influences of high-temperature and insensitive booster charges(HNS)were considered.Based on the air overpressure,witness plate wreckage and chemical-physical analysis of remained explosives on the scene,the explosive reaction levels of PBX-C04 was assessed comprehensively,and the influences of high temperature and booster charge were studied.The results show that PBX-C04 at room temperature exhibits excellent safety characteristic under high-speed fragment impact,it merely reacted to burning when impacted by a fragment with velocity up to 1970 m·s^(-1).When the booster charges of HNS was included,the reaction levels of PBX-C04 correspondingly deteriorated into deflagration.However,when heated to 200℃before impact test,the high-speed impact safety of PBX-C04 equipped with booster charge deteriorated remarkably into detonation.
