摘要: 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。Abstract: Theexistentshot-lineconceptwasextendedbasedonthevisualC~(+ +)and Matlab codes.Acomputationalmethodwasdevelopedbysettingupthecomputationalmodelofthedamage fieldparameters,whichconsistingoftheinitialvelocity,dispersiondirection,velocityattenuation, andsoon,forthepreformedorhalf-preformedfragmentwarheadattackingthetarget,andthetransformationofthefragmentpowerparametersinthespacecoordinate.
