摘　　要：为获得锥角药型罩壁厚对形成侵彻体特性的影响,在战斗部其他参量不变的情况下,针对不同的锥形药型罩壁厚建立计算模型,应用LS-DYNA数值仿真软件对侵彻形成过程进行仿真,结果表明对于一定锥角的大锥角药型罩,随着壁厚的增加所形成侵彻体头部速度和头尾速度差增大,所形成的侵彻体由EFP逐渐过渡为高速杆直至射流,为多模聚能战斗部的结构设计提供参考。In order to obtain the Angle shaped charge liner thickness effects on penetration will form features. In the warhead under the condition of other parameters constant, for different cone type shield wall thickness calculation model is set up,using Ls-dyne numerical simulation software simulation on formation process of penetration,results show that the big cone angle for a certain angle shaped charge liner,with the increase of wall thickness formed by the penetration of body head and tail velocity difference speed increase,formed by the penetration of body by EFP gradually transition to high speed rod until jet,the multiple model can provide reference for structure design of warhead.
