摘　　要：用冲塞试验评价大药量装药在撞击、剪切、绝热加热等综合作用条件下的安全性。用火药加速装置对试件加速,并通过高速摄像机拍摄炸药试验件跌落撞靶、点火等试验过程,利用冲击波压力传感器测试冲击波超压表征炸药试验件的反应程度。结果表明,PBX-1炸药在撞靶速度高达37.6m/s时没有发生反应,且PBX-2炸药在撞靶速度为27.7m/s时发生了爆燃反应,在撞击速度低于25.5m/s时未发生反应,说明PBX-2炸药的冲塞试验撞击感度高于PBX-1炸药。Spigot test was used to assess the safety of large explosive charges subjected to combined mechanical impact and shearing and adiabatic heating.The test assembly was accelerated via a powder-driven gun design.The process of impact and ignition was analyzed by high-speed video system.Blast pressure gauges were used to measure the blast wave overpressure of explosive for characterizing the reaction extent of explosive assembly.The results show that no reaction takes place for TATB-based polymer bonded explosives（PBX-1） at velocity up to 37.6m/s,and HMX/TATB-based polymer bonded explosives （PBX-2） take place deflagration at a velocity of 27.7m/s,and no reaction at velocity less than 25.5m/s,showing that PBX-2 were more sensitive than PBX-1 in the spigot test.
