摘要

研究了刚性圆锥头弹体贯穿延性金属靶板的冲击力学特性

将侵彻过程分为3个阶段

利用圆柱形空腔膨胀理论建立了侵彻方程

得到了各阶段弹体的过载和能耗的表达式.对4种不同厚度的铝合金靶板的锥形钢弹贯穿试验算例进行了理论和仿真计算

对所得结果与试验数据作了对比

结果显示三者一致性较好.分析了弹体在不同阶段的过载特性和影响因素

为尖形弹体及小型装药的侵彻过载特性评估提供了理论参考和分析方法.

Abstract

The impact characteristic of projectiles perforating plastic metallic plates was studied.Based on cylindrical cavity-expansion theory

a new engineering model considering three interconnected perforation stages was presented.Formulas of perforation acceleration and dissipative energy were derived.Perforation experaments have been performed by SIMLAB Norway on AA5083-H116 aluminum plates with four thicknesses.Calculation with new model and simulation were carried out.The analytical and numerical results were compared to the experimental findings

and good agreement was in general obtained.The deceleration characteristics in different porferation stages of projectiles were analyzed.Theoretic reference and analytical method were provided for deceleration characteristic evaluation of sharp-nose projectiles and small mass charge.
