摘　　要：针对钨合金破片、PTFE基含能破片和Zr基非晶合金含能破片撞击起爆屏蔽B炸药阈值问题,开展了弹道枪实验。结果表明,在实验中的弹靶条件下,上述3类破片的起爆速度阈值分别为1957、1717和1680 m/s。2类含能破片均能产生起爆增强效应,Zr基含能破片的起爆能力更强。标定了速度阈值计算模型中的关键参数,解耦了含能破片终点毁伤过程中动能和化学能占比。该研究结果可为杀伤战斗部破片选型和威力设计提供依据。This paper carries out a ballistic gun experiment to obtain the velocity threshold which is required for shock initiation of shielded composition B impacted by tungsten alloy fragments,PTFE-based energetic fragments and Zr-based amorphous alloy energetic fragments.The result shows that,under the specific target conditions of the experiment,the initiation velocity thresholds of the above three types of fragments are 1957 m/s,1717 m/s and 1680 m/s respectively.Both types of the energetic fragments can produce enhanced initiation effect,in which the Zr-based energetic fragments have a stronger initiation ability.The key parameters in the calculation model of the velocity thresholds are calibrated.The proportion of kinetic and chemical energy in the terminal damage process of the energetic fragments is also decoupled.The conclusion can provide guidance for fragment selection and power design of lethal warheads.
