起爆方式对子母式战斗部破片速度影响的数值分析

Numerical Analysis of the Velocity Affected by Initiating Mode on Cluster-type Warhead Fragments

为研究起爆方式对子母式战斗部破片速度分布及增益的影响,利用LS-DYNA软件对子母式战斗部的爆炸进行了数值模拟,并就不同起爆方式对破片速度分布及增益的变化进行了对比分析与研究。结果表明,两端同时偏心起爆的方式为最优起爆方式,破片速度增益最大;其次是偏心线起爆;最后是一端偏心起爆,可为战斗部设计提供参考。

To study the initiation cluster warhead fragment velocity distribution and the increase, the use of LS-DYNA software cluster-type warhead explosion of a numerical simulation, and different ways of initiating fragment velocity distribution changes and increase a comparative analysis and research. The results show that off-center initiation of both ends is the best option, followed by off-center line initiation, one end off-center Initiation is final. The results of this paper can provide a useful reference on engineering design for the warheads.
