战斗部破片对目标打击迹线的计算方法

A visual C～(++) and Matlab-based computational method for shot-lines of warhead fragments to a target

提出了破片对目标打击迹线概念,通过建立预制或半预制破片战斗部对目标杀伤作用场参数的计算模型,以及在空间坐标系下破片各威力特性参数的相互转换,得到了一种破片打击迹线的计算方法,并基于VC和MATLAB联合编程实现了战斗部破片打击迹线作用场的分布计算。通过破片对目标打击迹线可定量分析战斗部所有破片的整个空间分布,并直观描述每个破片的飞散方向、能量衰减及对目标打击能力变化情况,从而可精确地评价破片对目标不同要害位置处的打击效果。该杀伤作用场参数计算模型和破片对目标打击迹线计算方法可用于战斗部起爆姿态选择和对不同目标杀伤效果的威力评价,为战斗部方案设计和战斗部终点毁伤效应分析计算提供了新的参考依据和技术途径。

The existent shot-line concept was extended based on the visual C- （＋＋） and Matlab codes. A computational method was developed by setting up the computational model of the damage field parameters, which consisting of the initial velocity, dispersion direction, velocity attenuation, and so on, for the preformed or half-preformed fragment warhead attacking the target, and the trans- formation of the fragment power parameters in the space coordinate. And a new computational method was achieved to predict the shot-line field distribution of the fragment warhead by using the combined program with visual C-（＋＋） and MATLAB. A computational example was given by applying the achieved computational method to determine the shot-line field distribution of the fragment warhead under different explosion conditions attacking the plane target. The computational results described distinctly the damage field distribution of the warhead fragments to the plane and reflected visually the trajectories and energy attenuations of all the warhead fragments. The achieved computational method was validated by the comparison between the computational data with the known experimental results. This research can provide a new reference for the warhead design and terminal damage effect analysis.
