起爆方式对双聚焦战斗部性能的影响

为了分析起爆点数量和位置对双聚焦式战斗部破片飞散特性的影响,对某型号的双聚焦式破片战斗部进行了数值仿真,仿真结果与试验值具有较好的一致性,对比分析了采用不同起爆方式时破片的飞散特性. 研究结果表明,轴向起爆时改变起爆点的位置和数量对破片初速影响小,对聚焦效果影响大;采用偏心起爆时,破片初速与起爆半径成正比关系,起爆点的周向夹角对破片飞散特性影响小,偏心轴向上起爆点数量和位置影响较大. 适当改变起爆点位置和数量能优化破片飞散,增强聚焦带对目标的毁伤作用. 

Effect of Initiation Manners on Scattering Characteristics of Double-Beam Focusing Warhead

In order to study the effects of quantities and position of initiation points on double-beam focusing warhead, numerical simulation was conducted on a certain double-beam fragment focusing warhead. The simulation results were accordant well with the test results. The fragment scattering characteristics under different initiation manners were made comparison and analysis. The research results show that when taking axial initiation, the quantity and position of initiation points have less effect on the fragment velocity, large effect on the focusing effects of fragment. When using eccentric initiation, fragment velocity is proportional to the detonation radius, the quantities and location of initiations in the eccentric shaft have much effect on the fragment scattering characteristics than the circumferential angle of initiation point. The fragment scattering can be optimized and the damage effect caused in fragment focal zones can be enhanced by changing the quantities and location of initiation points appropriately.
