摘　　要：为揭示活性破片穿透前靶后,对后效靶板的耦合能量分布特征及机理,开展活性破片毁伤双层靶板弹道枪实验。通过高速摄影记录弹靶作用行为,结合间隔靶毁伤形貌、破片侵靶破碎理论和二次碎片能量分布,建立活性破片作用后效靶板毁伤行为模型。研究结果表明,活性破片在毁伤后靶过程中,动能化学能分别在不同碰撞速度区间内占据主导地位,随碰撞速度增加,活性破片被完全激活,活性破片对后效靶板的毁伤从化学能主导转变为动能主导。To reveal the coupling energy distribution characteristics and mechanism of the reactive fragments penetrating the rear target plate,the ballistic gun experiment of the reactive fragment impacting the double-layer target plate is carried out.The bullet-target interactive behavior is recorded with high-speed photography,and a damage behavior model of the reactive fragments impacting the rear target plate is established based on the damage effect of target,the fragmentation theory of the fragments penetrating the target,and the secondary fragment energy distribution.The results show that the kinetic and chemical energies predominate in different impact velocity intervals during the process of reactive fragments impacting the rear target plate.With the increase in impact velocity,the reactive fragments are fully activated,and the damage of reactive fragments to the rear target plate changes from chemical energy to kinetic energy.
