摘　　要：本文提出了一种新型电磁发射拦截弹,以拦截弹与钨合金长杆弹碰撞过程为例,使用LS-DYNA程序建立了拦截弹和钨合金长杆弹的三维有限元模型。在拦截弹对钨合金长杆弹的拦截效果问题上进行了数值模拟分析,并得出了不同着角和钨合金长杆弹运动速度对拦截效果影响的关系曲线,给出了拦截弹与钨合金长杆弹碰撞后的速度变化及状态改变情况,结果表明,拦截弹对钨合金长杆弹起到了较好的拦截作用,两者碰撞后,钨合金长杆弹对装甲车辆的穿甲效果明显降低。This paper presented a new electromagnetic launching interception projectile,taking the process of interception projectile impacting on tungsten-alloy long rod as an example,a 3-D finite element simulating model for the interception projectile and tungsten-alloy long rod was set up by using the LS-DYNA procedure.Through numerical simulation study on the interception effect of interception projectile on the tungsten-alloy long rod target,the interception effect under different interception angles and tungsten-alloy long rod velocities was attained,then the changes of velocity and performance were analyzed after interception projectile impacting against armour-piercing.The results reveal that the interception effect was well,and directly affected the piercing effect after impacting.
