Title The Metal detonating cord into three detonate a network Synchronization Study
Abstract
Metal detonating cord through a uniform system of cable pulling machine, charge density can better achieve consistency, and so on through the series-parallel network connections can be built detonator certain structure. In this paper, prepared by the experimental detonating cord, booster reliable test, synchronization experiments to study the properties of the metal detonating cord and a synchronous-three initiation into the network. In the preparation of test detonating cord, using RDX, 8701, A5 three explosive core of medicine,, lead-antimony alloy as the shell material, the cable machine evenly drawn into a fine detonating cord, by measuring the length and diameter to study its charge density. Then detonating cord respectively different diameter cored and performance research and booster reliability test instrument measured obtaining the use of detonation velocity detonation velocity, obtaining power and booster through stereotype dent reliability test and measurement grid perforation test Finally, design a detonator into three networks, the use of multi-channel high-speed dynamic test system synchronization research, draw conclusions and evaluate the test and analysis.

1.1研究背景
1879年，导爆索首次出现，一百多年时间过去了，随着炸药成分和爆破技术的不断进步，导爆索不断改进并飞速发展。1897年，以硝化棉作为药芯，金属作为外壳的导爆索开始出现，该导爆索首先被应用于采矿业。随着军事方面需求的牵引和工艺技术的驱动，导爆索不断发展。1904年，装药药芯为TNT，外壳为金属铅的导爆索开始出现。1906年，装药药芯为苦酸，外壳为金属锡的导爆索开始出现。1919年，药芯装药为黑索金和太安的导爆索首次出现，由于黑索金和泰安爆速高、威力大、感度高，这使得导爆索的性能得到很大改善[1]。
