Abstract

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.
