The Effect of Shell Configuration on the Formation of Multimode Penetrators

摘要

Adopting center point and annular multi-point initiation mode,the influence of shell thickness towards formation parameters of multimode penetrators,such as velocity and length-diameter ratio,was researched by using LS-DYNA software.The best results of shell thickness are found to form good EFP and JPC with the same shaped charge structure.When the shell thickness is 0.04～0.05Dk,the good penetrators can be formed.It obtained the change curve of the formation parameters of penetrators with the shell thickness.The result can offer reference for the further study of multimode shaped charge.
