摘　　要：使用LS-DYNA和AUTODYN仿真软件对EFP战斗部的侵彻效应和靶后破片效应进行仿真分析,得出横向速度对掠飞攻顶弹药EFP毁伤效应的影响规律:侵彻深度随着横向速度的增大而减小;横向速度能增加靶后有效破片数量,导致靶后破片云向横向速度方向偏移。In order to explore the influence of transverse velocity on EFP damage effect of swept top attack ammunition,LS-DYNA and AUTODYN simulation software were used to simulate and analyze the penetration effect of EFP warhead and the fragment effect after target respectively.The influence law of transverse velocity on EFP damage effect was obtained:the penetration depth decreases with the increase of transverse velocity,the transverse velocity can increase the number of effective fragments after the target,and the transverse velocity will lead to the deviation of the fragment cloud to the transverse velocity direction after the target.
