用电磁粒子速度计实验研究一种TATB基钝感炸药的冲击响应
Experimental Study on the Shock Response of a TATB-based Insensitive Explosive with Electromagnetic Particle Velocity Gauge
摘要
Abstract
Aiming at a new TATB based insensitive explosive(Tx), the particle velocity history and shock wave trajectory in explosive under three kinds of loading states, including explosive loading directly, increase of organic glass partition and explosive driven flyer, were measured by a combined electromagnetic particle velocity(EMV) gauge testing technology.According to the test results, the impact response process of explosive under different loading pressure was analyzed.The results show that when the explosive is loaded directly, the loading pressure is the highest.Tx insensitive explosive soon reach the state of detonation, the distance to detonation is about 1.5mm.After adding organic glass partition,when the loading pressure is 14.2GPa, the velocity of explosive particles is more consistent with the direct loading, the distance to detonation of Tx insensitive explosive is significantly increased to about 5mm.In the explosive driven flyer, when the loading pressure is 9.5GPa, the particle velocity of Tx explosive is gradually decreased,and exist a certain passivation phenomenon, the distance to detonation is more than 20mm.关键词
