射弹冲击引爆反应装甲数值模拟研究

A Computional Study of Explosive Reactive Armor Initiated by Projectile

利用 LS—DYNA 有限元计算程序对射弹引爆双层反应装甲作用过程进行了数值模拟,分别计算了不同头部形状、不同入射角条件下射弹对双层反应装甲的作用过程及其引爆临界条件。从计算结果可以看出,射弹头部形状及入射角均对引爆结果产生很大影响。文中对上述影响关系进行了简要的分析和总结,文中的研究结论将为反装甲武器系统设计者提供有益的借鉴与参考。

Applying the LS-DYNA process,we studied the process that the projectile initiated the double layers explosive reactive armor through simulation.The process which the projectile act on the armor,and the critically initiated condi- tion are calculated respectively when the head shape and the angle of projectile's incidence are respectively different.As shown from the result,the head shape and the angle of projectile's incidence have great influences to the initiated re- sult.These influences are analyzed and summarized briefly in this dissertation.And the study conclusion will provide the anti-armor designer helpful use for reference.
