ANSYS聚能装药截流装置结构设计

摘要聚能装药截流装置实际上是一个反向聚能装药结构，是用来切断射流低速部分和杵体，只允许射流高速部分通过的装置。在逆序起爆串联聚能装药战斗部中，通过截流装置使二级射流的尾部速度大于规定要求，并且不影响射流头部的形成，是保证两级射流不发生相互干扰、提高对靶板侵彻的重要装置。70152

本课题针对聚能装药截流装置开展聚能射流成型和对聚能射流截流过程研究，利用定常理论，PER 准定常理论，药型罩压垮一般性理论理论和 ANSYS 进行数值仿真模拟，调整截流装置的材料和壁厚，设计出合理的聚能装药截流装置，最后基本得到可行的设计方案。

Title Shaped charge closure device structure design

Abstract Shaped charge closure device is actually a reverse shaped charge structure, is used to cut off the low speed jet and slug, only allows high-speed jet through the device. In reverse order initiation tandem shaped charge warhead, the shutoff device enable secondary jet tail velocity was larger than the prescribed requirements, and does not affect the formation of jet head, is to ensure a level two jets do not interfere with each other, improve an important device of the projectiles.

This topic for cumulative installed medicine closure device to carry out the shaped charge jet molding and study of shaped charge jet during the closure, by using the theory, per the quasi steady theory, the medicine cover overwhelmed by the general theory and ANSYS numerical simulation, material and wall thickness of the adjusting cut-off device, design a reasonable charge cut-off device.

Finally, the basic feasible design scheme.
