摘    要:设计建立了一种炸药大药片撞击感度试验方法,落锤质量为20 kg、落高度为0~15 m,对规格20 mm5 mm、重约2.8 g的大药片进行撞击感度测试。试验测试了两种典型炸药Tetryl和JOB-9003炸药的落锤撞击感度,落锤撞击Tetryl炸药和JOB-9003炸药的爆炸阈值落高分别约3.5 m和6.5 m。对落锤撞击JOB-9003炸药样品的过程进行了数值计算,计算结果与试验值相符。试验结果表明,该试验方法可以测量炸药的落锤撞击感度。

关 键 词:爆炸力学    撞击感度    落锤    大药片

Abstract:A method of drop hammer impact sensitivity test for big-bill explosive was developed. The weight of the hammer was 20 kg and the drop height was between 0 ~ 15 m. The size of big-bill explosive was20 mm5 mm and its weight was 2.8 g. Tetryl and JOB-9003 explosives were tested. The threshold heights of ignition for two explosives were 3.5 and 6.5 m respectively. The course of impact for JOB-9003 was simulated. The calculational result well agreed with the test. The test results show this test method can be used to measure the drop hammer impact sensitivity for explosives.
Keywords:mechanics of explosion  impact sensitivity  drop hammer  big-bill explosive
