| 摘 要： | 为反映线性爆炸成型侵彻体（liner explosive formation penetration,LEFP）成型及侵彻过程中各参数的变化规律,合理设计LEFP装药结构参数,利用LS-DYNA 3D有限元动力分析软件,采用任意拉格朗日-欧拉（ALE）算法,建立包括炸药、药型罩、壳体、空气、靶板在内的三维数值模型,在分析线性爆炸成型侵彻体成型过程的基础上,通过数值模拟和实验进一步分析了LEFP对45#有限钢靶板的侵彻效应。结果表明,该模拟方法正确,能为LEFP的设计提供参考。

| Abstract: | In order to reflect transforming rules of parameter in the course of the forming and penetration of LEFP,through reasonable designing of parameters of LEFP,use LS-DYNA 3D finite element analysis software and the arbitrary Lagrangian-Eulerian(ALE) to establish three-dimensional numerical model including dynamite,liner,cover and air.Based on analyzing the process of liner explosive formation penetration(LEFP) formation,research on 45 steel target penetrated by LEFP,numerical simulation was in accordance with ... |
