摘要
为了研究聚能装药药型罩锥角对聚能杆式弹丸(JPC)与金属射流(JET)形成的影响,设计了具有不同锥角药型罩的聚能装药结构,基于LS-DYNA数值仿真软件,采用ALE算法进行数值仿真。同种装药结构(包括药型罩结构参数)下,通过对药型罩锥角的改变实现聚能杆式侵彻体和金属射流之间的转换,研究JPC与JET的形成及转换临界条件,为多模战斗部聚能装药结构的设计提供参考。
In order to study the influence of penetrating body （JPC） and metal jet （JET）, the shaped charge liner cover angle of cone on the cumulative rod JET formation, different angle of cone shaped charge liner of shaped charge structure was designed, based on the ANSYS/LS-DYNA numerical simulation software, with numerical simulation by ALE algorithm . In the same charge, JPC and JET were formed by different detonation initiation ways, study the formation and the transformation of critical conditions between JPC and JET, for the design of the structure of the multi-mode warhead upon the reference.
