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。

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.
