长杆弹侵彻新型复合装甲数值仿真及研究

摘要

应用有限元计算程序AUTODYN模拟了由爆炸反应装甲和陶瓷复合装甲组成的新型复合装甲在长杆弹斜侵彻作用下的侵彻过程.根据长杆弹与爆炸反应装甲和陶瓷复合装甲的作用现象,研究了长杆弹对新型复合装甲的侵彻机理以及两者在各时刻的作用规律.所得结论对进行其他复合装甲抗长杆弹侵彻的研究具有一定的参考价值.%This paper uses AUTODYN finite element software to simulate the penetration of new pattern composite targets made of explosive reactive armor (ERA) and ceramic targets by long rod projectiles. The penetration mechanism and penetrating rule are studied based on the physical phenomena of interaction between long rod projectiles and ERA and between the remaining projectiles and ceramic targets. The result provides insights to investigations on the penetration of other composite targets and rod penetrations.
