摘要/Abstract

摘要： 提出一种超聚能射流形成的理论计算方法，给出了附加装置材料密度、厚度和药型罩锥角、密度、厚度与超聚能射流速度、有效质量之间的关系。基于非线性显式动力学分析软件AUTODYN，进行了超聚能射流形成过程数值模拟，其结果与理论计算结果基本一致。通过超聚能射流侵彻试验，证明试验结果与数值模拟结果吻合较好。研究表明：在一定范围内，随着药型罩锥角的增大，超聚能射流速度逐渐减小、质量逐渐增大；超聚能射流速度、有效质量及侵彻能力远大于传统聚能射流。

Abstract: A theoretical calculation method for the formation of hyper shaped charge jet is proposed. The theoretical relations among material density and thickness of additional body, and cone angle, material density and thickness of truncated liner and the velocity and effective mass of hyper-accumulation shaped charge jet are given. The simulated results of the formation process of hyper shaped charge jet based on AUTODYN software are basically the same as the theoretically calculated results. The numerical results of hyper shaped charge jet penetration are in good agreement with the experimental results. The results show that, within a certain range, the velocity of hyper shaped charge jet decreases and its mass increases with the increase in cone angle; the velocity, effective mass and penetration ability of hyper shaped charge jets are much larger than those of classical shaped charge jets.
