Abstract

The structure and principle of the explosive device is described simply.all the process during this test is recounted in detai 1 .and the results of the test are analysed in this article. The test device is a colurnn.with a diameter of 150mm and a length of 300mm. which shell is made of a steel or a glass fibre reinforce plastic.with a thickness of 5mrn.in it there is prefab filler.ln the centre of the shell,there is a cylindrical high energy explosive,and in the end there is a high voltage exploder. The test device is illuminated by the laser pulse produced with a ruby sequential pulse laser. The record is conducted by a high speed camera Type GSJ.The test device. the sequential pulse laser generator and the high speed camera are synchronized by a self-made synchronizer .In al 1 the process three pictures are taken which interval are 48js.Therefore.the conclusion can be obtainned. that is.the test device bursts in symmetry and shaped like drum.and then it flies off, so t.hat some useful information is offered for studyimg and design of explosive device.
