聚能射流冲击起爆屏蔽压装PBX炸药的试验研究
|
摘要
为了分析由聚能射流引起的两种典型屏蔽压装PBX炸药的冲击起爆感度,采用某Ф80mm制式破甲弹作为标准射流源,在炸高为150mm的条件下,对不同厚度45~#钢覆盖板屏蔽的PBX-1和PBX-2炸药进行了射流冲击起爆感度试验;采用"兰利法"对覆盖板的厚度进行选取,得到了聚能射流引爆两种典型压装PBX炸药的临界隔板厚度。结果表明,临界爆轰时,PBX-1炸药覆盖板厚度为35～40mm,PBX-2炸药覆盖板厚度为140～150mm,即PBX-1的临界隔板厚度比PBX-2炸药减少73.3%;PBX-1炸药起爆所需的射流能量为185mm~3/μs~2,远高于PBX-2炸药,因此PBX-1炸药的射流安全性显著优于PBX-2炸药。
To analyze the impact initiation sensitivity of two kinds of typical shelled pressed polymer boned explosives(PBX) caused by shaped charge jet, a Ф80 mm armor-piercing projectile was used as the standard jet source. Under the conditions of explosive height of 150 mm, the sensitivity tests of impact initiation of PBX-1 and PBX-2 explosives shielded by 45~# steel cover plate with different thicknesses caused by shaped charge jet were performed. The thickness of cover plate was selected by Langlie′s method. The critical diaphragm thickness of two kinds of typical pressed PBX explosives initiated by shaped charge jet was obtained. Results show that under the critical initiation, the thickness of shield plates covering PBX-1 explosive is 35—40 mm and that of PBX-2 explosive is 140—150 mm, that is to say, the critical thickness of PBX-1 explosive is 73.3% less than that of PBX-2 explosive. The initiation energy of jet required by PBX-1 explosive is 185 mm~3/μs~2, much higher than that of PBX-2 explosive, so the jet safety of PBX-1 explosive is obviously better than that of PBX-2 explosive.
