摘　　要：为了研究聚焦战斗部破片的聚焦性能,建立了计算破片速度和密度分布的数学模型,计算了破片速度和密度分布情况。设计聚焦战斗部试验弹。对端面起爆和偏心起爆两种不同起爆方式下聚焦破片战斗部的性能进行了验证试验。采用多通道测速仪测试战斗部的破片速度,进行了破片密度分布统计分析。结果表明,聚焦破片战斗部由端面起爆改为60°偏心起爆,破片速度和破片密度提高。In order to study the focusing performance of focused fragmentation warhead, a mathematic model of calculating the fragment velocity and density distribution was established and the fragment velocity and density distri- bution were calculated. The testing bomb of focused warhead was designed. The performance of focused fragmentation warhead under two initiation methods of the end surface initiation and eccentric initiation were tested and valida ted. The fragment velocity of warhead was measured by a multi-channel velocity tester. The statistical analysis of the fragment density distribution was performed. The result shows that fragment velocity and density are enhanced by changing detonation mode from end surface initiation to eccentric initiation in 60° .
