Abstract:

为分析新型高能钝感炸药2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)的射流冲击感度,在口径为56mm的聚能装药和炸高为80mm条件下,进行了45#钢隔板覆盖下无围压炸药冲击起爆感度实验。用“Langlie法”获得了ANPyO临界起爆隔板厚度,用AUTODYN计算了临界头部速度和射流直径,标定了ANPyO的临界起爆阈值,并与8701炸药的试验结果作了比较。结果表明:临界爆轰时,8701炸药覆盖的45#钢隔板临界厚度约160mm,ANPyO炸药的临界隔板厚度约为68mm,比8701降低了约57.5%。ANPyO炸药的临界速度为3.7mm·μs-1,射流头部直径为4.8mm,临界冲击起爆阈值约为32.3mm3·μs-2,8701为7.16mm3·μs-2,ANPyO为8701炸药的4.5倍,可见ANPyO钝感于8701,是一种低射流起爆感度炸药。
