Influence of Sequential Initiation Parameters on Damage Effectiveness of Aimed Warhead

  • 摘要: 为提高定向战斗部的毁伤效能,明确序贯起爆参数对定向战斗部毁伤效能的影响,运用LS-DYNA有限元程序,采用破片速度差累加和飞散角累加的方法,研究了不同序贯起爆参数下破片初始威力参数,利用毁伤概率法,计算了不同序贯起爆参数下战斗部对地面军用车辆的毁伤效能。结果表明:起爆线个数和起爆线夹角主要影响破片速度大小,起爆延时时间主要影响破片速度大小和飞散角正负占比。相对于偏心一线和三线序贯起爆,偏心两线序贯起爆在落高为7~9 m时有7.5~25.0 m2的毁伤面积。当起爆线夹角由30°增大到120°,落高为4~8 m时,战斗部对地面军用车辆的毁伤面积降低3.9%~60.3%。序贯起爆的延时时间由零增加到0.75倍的相邻起爆点间爆轰波传播时间,落高为4~8 m时,战斗部的毁伤面积增加8.4%~87.2%。当起爆方式采用偏心两线序贯起爆,起爆线夹角取30°~60°,延时时间取0.50~0.75倍的相邻起爆点间爆轰波传播时间时,破片战斗部对地面军用车辆目标具有较好的毁伤效能。
