壳体参数对炸药快速烤燃响应的影响

The Influence of Shell Parameters on Fast Cook-off Reaction of Explosives

对不同壳体直径与不同壳体约束的TNT与PBXN-109两种炸药进行了快速烤燃试验。试验结果显示:在固定壳体约束条件下,壳体直径对炸药烤燃响应无影响,炸药烤燃特性仅由炸药自身特性决定;不同壳体约束对炸药的烤燃响应有影响,随着壳体约束增强,炸药的快速烤燃等级增强;炸药的快速烤燃响应特性由炸药自身特性和壳体约束决定。

Fast cook-off test of TNT and PBXN-109 explosives with different shell diameters and different shell constraintswere both carried out, the test results show that the shell diameters have no influence on fast cook-off reaction of explosive, fastcook-off reaction is only decided by the characterities of the explosives itself, but the shell constraints have some influences. Thestronger the shell constraints ,the higher the explosives’fast cook-off reaction level. The study indicate that explosives’fast cook-offreaction is decided by the characterities of the explosives and the shell constraints.
