在过去六年中Hunting Engineering Limited(HEL)开发了一套以二维解析模型为基础的计算机程序,用以计算成型装药射流从虚拟点开始经过连续状态到断裂等一系列变化过程。二维射流表达程序可与一种或多种靶板响应解析模型(包括均质靶、间隙靶、层状主动装甲或爆炸装甲)联用。射流形成和靶板响应模型已被大量的检验射流特性和靶板行为的试验所证实。本文以图解法说明射流和爆炸装甲计算机程序的应用,这些程序可用来确定特种战斗部对特种装甲板的作用或研究各种参量对不同射流和靶板性能的影响。对每个解析程序都建立了图解子程序,并给出输出结果的实例。 本文描述了该程序用于从参量上检验一个爆炸装甲实例的响应结果,这种结果作为成型装药射流侵彻角度、对靶板的炸高、头部速度及射流材料的函数。对于双重或多重爆炸装甲组,程序计算了由前部靶板出来射流的特征,然后计算经过靶板间隙的发展过程。每个靶板响应结果均以一个新的射流状态的函数进行计算。参量研究的各种状态均已进行实验,并且给出了闪光照像资料,用以对实验与计算结果进行比较。
Over the past six years, Hunting Engineering Limited (HEL) has developed a two-dimensional analytical model-based computer program to calculate a series of changes in the charge flow from the virtual point through the continuous state to the fracture. Two-dimensional jet expression programs can be used in conjunction with one or more target response models (including homogeneous targets, gap targets, layered active armor or explosive armor). Jet formation and target response models have been demonstrated by a large number of tests to verify jet characteristics and target plate behavior. This article illustrates the application of computer programs for jetting and explosive armor that can be used to determine the effects of special warheads on special armor plates or to study the effect of various parameters on the performance of different jets and targets. A graphical subroutine is created for each resolver and gives examples of the output. This paper describes the procedure for verifying the response of an explosive armor instance from a parametric model as a function of penetration penetration of the shaped charge jet, target height, head velocity, and jet material. For double or multiple explosive armor groups, the program calculates the jet characteristics from the front target and then calculates the evolution through the target gap. The response of each target is calculated as a function of a new jet state. Various states of parametric studies have been experimented, and flash photographic data has been given to compare the experimental and computational results.
