摘要:本文利用三维有限元程序对线型聚能射流的形成过程进行数值模拟,分析了线型聚能装药的射流及其杵体的速度、密度等参数的分布特性,并对射流和杵体在飞行过程中的断裂现象进行了分析讨论。这对进一步展开对线型聚能装药的理论研究具有一定的指导作用。
Abstract:This paper takes advantage of 3D explicit finite element method to simulate the process of linear shaped charge jet formation. The distributing characteristics of varied parameters, such as velocity and density, in the shaped charge jet and slug are analyzed. The break-up phenomena in the jet and slug during their flight process are also discussed. It is helpful to theory investigation of linear shaped charge.
