摘　　要：为研究子弹膛内抛射,以某新型结构防空榴弹战斗部为基础,建立含能子弹膛内抛射过程数值模拟数学模型,运用ANSYS/LS-DYNA软件模拟火药燃烧、推板及含能子弹在膛内的运动过程,得到各层含能子弹出膛时相对速度曲线,并将模拟结果与理论估算值进行比较。结果表明:模拟数据可为其结构设计和毁伤威力计算提供参考。In order to study the processes of projecting bullet in bore, the numerical simula- tion model of the projecting energetic bullet in bore is established in this paper, based on a new structure of antiaircraft shrapnel warhead. The processes of the gunpowder combustion, pushing board and energy bullet＇s movement in bore are simulated, using ANSYS/LS - DY- NA software. The relative velocity curves of the energetic bullets in each layer can be ob- tained. The simulation results are compared with theoretical estimates. The simulation results can provide a reference for the structure design and damage power calculation.
