装药参数对多点起爆切割药型罩的影响
|
摘要
多模可调战斗部是新型智能弹药发展趋势中重要的一类,可实现爆炸成型弹丸与多破片之间的转换。基于LS-DYNA有限元计算软件,研究了多点同步起爆所产生的爆轰波切割药型罩机理,分析了起爆方式和炸药种类对切割效果的影响。结果表明:相对于平面排布,起爆点呈曲面排布时,爆轰波切割药型罩所形成的多破片毁伤能力更强;与其他常用炸药相比,以梯恩梯为主装药时形成多破片的效果更好。
The multimode adjustable warhead is an important category in the development of new smart ammunition,which enables conversion between EFP and multiple fragments. Based on the finite element calculation software LS-DYNA,the mechanism of cutting the liners by multi-point simultaneous detonation waves is studied,and the influences of the detonation mode and the type of explosive on the cutting effect are analyzed. The results show that the multi-fragments formed by the detonation wave cutting the liners have stronger damage ability when the detonation points are arranged on a curved surface compared with the plane arrangement; compared with other common explosives,EFP is better to form multiple fragments when TNT is used as the main charge.
