ansys聚能装药与新型爆炸反应装甲作用过程研究

摘要随着各类穿甲武器的发展，装甲的防护性能也在不断提高。为了研究聚能射流与新型爆炸反应装甲的作用机理,本文采用三维有限元程序（ansys/ls-dyna）模拟聚能射流与新型爆炸反应装甲的作用过程。首先通过设计不同结构的聚能装药，分析不同装药直径对于射流成型的影响，研究其头部速度与头部直径，发现当装药直径越小时，射流的头部速度与头部直径就越低，动能也就越低，对靶板的侵彻能力就越弱。然后基于 M.Held 单层爆炸反应装甲引爆判据,在不同装药直径的射流基础上加入新型爆炸反应装甲进行模拟分析，并结合理论计算，建立了射流侵彻新型爆炸反应装甲起爆判定准则。69552

Title A research for the process of new explosive reactive armor with Shaped Charge

Abstract

With the development of various types of armor-piercing weapons, armor protection performance is improving. To study the mechanism of action about shaped charge and new explosive reactive armor. In this paper, using three-dimensional finite element program (ansys / ls-dyna) simulation the effect process of a shaped charge with new explosion reaction armor. First, by designing different structures shaped charge, analyzing the effect of different charge diameter for forming shaped jet. Study on the head speed and the diameter of the head, it found that when the charge diameter is smaller, the lower head speed and head diameter, the lower kinetic energy and the weaker capability of jet penetrate target plate. And then based on M.Held single explosive reactive armor detonation criterion, it was added a new explosive reactive armor based on the different diameter of charge jet, Simulation analysis combined with theoretical calculations, the detonation equivalent method of jet penetrating new explosive reactive armor was established.

Keywords New explosive reactive armor，Detonation criterion，Mechanism of action
