传爆药冲击波感度试验方法的简化研究

摘要

A new type of small scale gap test method ( SSGT) , in which RDX was substitutedby A-IX-I [ m( RDX)︰m(insensitive agent) =95︰5]as donor casts, wasintroduced to study thesensitivity of shock wave. The explosion energy output performance of donor explosives was tested by a group of none gap tests. Result shows that the average mass of donor explosives is 1 195. 5 mg, and the relatively error is 0. 495%;the average pitting depth of identification slab is 1. 769mm, and relatively error is 0. 96%. It indicates that donor explosive has a good performance. This method was used to study the shock wave sensitivity of JH-14 before or after aging testsathigh temperatures. It shows that the aged explosives tend to have higher shock wave sensitivity, and the sensitivity increases with the increase of age time of accepters.%尝试了一种用压装A-IX-I(RDX与钝感剂质量比为95︰5)药柱替代纯RDX作为施主药柱进行冲击波感度试验( SSGT)的方法,通过零隔板试验,检验了施主药柱的爆炸能量输出性能。所得施主药柱的平均质量为1195.5 mg,相对误差0.495％；鉴定块的平均凹痕深度1.769 mm,相对误差0.96％,说明压装法得到的施主药柱性能较好。利用该方法研究了JH-14传爆药经过高温加速老化前后的冲击波感度,结果显示,老化后的样品冲击波感度具有增加的趋势。
