Numerical Analysis of Influence of Medicine Cover Structure on Cutting Depth

Abstract

In order to study the cutting depth influence of the medicine cover structure of the linear-shaped charge cutter, and to select the suitable medicine mask structure, the numerical simulation of eight kinds of structure of medicine mask was carried out by LS-DYNA software. Based on years of engineering experience, we design a new medicine cover structure for the linear cumulative cutter. The simulation experiment verifies the feasibility of the medicine mask structure designed in this paper when cutting the target plate, and also helps us to realize the essential process of linear-shaped energy cutting target. The results show that we have the maximum cutting depth and the excellent cutting effect when the medicine mask caliber is 35mm, the wall thickness $c$ is 1.5mm, the top drug high is 20mm, and the top width $b$ is 15mm.
