摘要: 为了从理论上得到给定初始条件下可变形战斗部的弹体变形型面,将战斗部变形部分的结构简化 为辅助装药对单层圆柱壳体作用的结构,将圆柱壳体作为理想刚塑性材料,建立圆柱壳体的五塑性铰位移模 式,应用刚塑性动力学原理,得到战斗部弹体变形型面的理论模型,模型计算结果与实验结果吻合较好。Abstract: Inordertoforecasttheoreticallythedeformationshapeofadeformabledirectionalwarhead onthegiveninitialconditions,thestructureofthedeformabledirectionalwarheadondeformingphase wassimplifiedasthesingle-layercylindricalshellwithadeformingcharge,andthecylindricalshell wasregardedasrigid-perfectlyplasticmaterial.A modelforanalyzingthedeformationshapeofthe deformabledirectionalwarheadwasestablishedbyusingthefive-plastic-hingedisplacementmodeof thecylindricalshellandtheprincipleofrigid-perfectlyplastic.Thetheoreticalresultsbythismodelagreewellwiththeexperimentalresults.
