摘　　要：为了深入研究HMX基和TATB基PBX炸药爆轰成长过程的差别,采用炸药平面透镜爆轰加载及空气与隔板综合衰减技术,建立基于锰铜压阻传感器的一维拉格朗日实验分析系统,通过实验确定了PBXC03炸药和PBXC10炸药的临界起爆爆轰加载装置,得到了PBXC03和PBXC10炸药在各自临界起爆压力加载条件下冲击起爆过程不同拉格朗日位置的压力变化历史。发现PBXC03和PBXC10炸药的爆轰成长过程存在明显区别:PBXC03炸药前导冲击波过后有明显的压力增长过程,而PBXC10炸药前导冲击波过后未能看到明显的压力增长过程,这一现象表明HMX基和TATB基PBX炸药冲击起爆及其爆轰成长的物理机制是不同的。In order to study deeply the difference of detonation growth progress between PBXC03and PBXC10explosives,a one-dimensional Lagrangian experimental system is established based on the Manganin piezoresistive pressure gauge measurement technique,in which the loading technique of explosive plane-wave lens and the attenuation technique produced by both air-gap and Al-gap are used. The shock initiation experiments are performed on the PBXC03and PBXC10explosives.Their detonation loading devices for critical initiation are determined and press histories at different positions under critical loading condition in shock initiation process are obtained.There are obvious press growth processes after shock wave in PBXC03,but not in PBXC10.It is shown that the shock initiation and detonation growth mechanism of the HMX-based and TATB-based plastic bonded explosives are different.
