Abstract

Theexistentshot-lineconceptwasextendedbasedonthevisualC~(+ +)and Matlab codes.Acomputationalmethodwasdevelopedbysettingupthecomputationalmodelofthedamage fieldparameters,whichconsistingoftheinitialvelocity,dispersiondirection,velocityattenuation, andsoon,forthepreformedorhalf-preformedfragmentwarheadattackingthetarget,andthetransformationofthefragmentpowerparametersinthespacecoordinate. Andanewcomputationalmethodwasachievedtopredicttheshot- linefielddistributionofthefragmentwarheadbyusingthecombinedprogram withvisualC~(++)andMATLAB.Acomputationalexamplewasgivenbyapplyingtheachievedcomputationalmethodtodeterminetheshot- linefielddistributionofthefragment warheadunderdifferentexplosionconditionsattackingtheplanetarget.Thecomputationalresultsdescribeddistinctlythedamagefielddistributionofthewarheadfragmentstotheplaneandreflectedvisuallythetra ectoriesandenergyattenuationsofallthewarheadfragments.Theachievedcomputationalmethodwasvalidatedbythecomparisonbetweenthecomputationaldatawiththeknownexperimentalresults.
