新型高能钝感炸药JBO-9X在较高冲击压力下冲击起爆过程的实验研究
Experimental Study on Shock Initiation Process of a New Insensitive High Explosive JBO-9x under High Impact Pressure
摘要
Abstract
A high-speed scanning camera and wedge-shaped explosive configuration were used to study the shock initiation process of a new insensitive high explosive JBO-9X.The experimental results were numerically simulated and verified by LS-DYNA software.Results show that under the incident shock pressure of 6.9GPa,the time of shock to detonation of JBO-9X is 1.5μs and the distance of shock to detonation is 7.9mm.When the shock wave just goes into the explosive,the ratio of occurred chemical reaction (λ)is 0.2.With increasing the distance of shock wave entering the explosive,the ratio of the chemical reaction occurred in the tested explosive increases gradually. Under the experimental conditions,when the incident shock pressure is 6.85GPa,the distance of shock to detonation of JBO-9X is 8.0 mm.The growth curve of chemical reaction ratio with the distance of the shock wave entering the explosive is basically the same as the experiment.关键词
