    摘要:

    为了研究活性破片在侵彻Q235钢靶过程中对靶后目标的毁伤特性,以油箱和棉花为目标,选取主成分为W和Zr的3种活性破片进行了弹道枪实验。实验结果表明,活性破片侵彻靶板时具有扩孔效应,相同条件下Zr含量高的活性破片引燃棉纱和油箱效果较好。基于活性破片穿燃毁伤过程,提出了用火球明亮区域纵向剖面面积来表征活性破片释能速率的方法,获得了活性破片形成的火球横向最大直径和纵向最大直径变化规律。

    Abstract:

    In order to study the damage characteristics of the active fragments to the target behind the Q235 steel target in the process of penetration, with the fuel tank and cotton as the target, three different active fragments with W and Zr as main components were selected for ballistic gun experiments. The experimental results show that the active fragments have a hole-expanding effect as penetrating the target plate. Under the same conditions, the active fragments with higher content of Zr have a better effect on igniting cotton yarn and fuel tanks. Based on the burn-through and damage process of the active fragments, a method was proposed to characterize the energy release rate of the active fragments by the longitudinal cross-sectional area of the bright area of the fireball, and the maximum horizontal and vertical diameters change rules of the fireball formed by the active fragments were obtained.
