【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。更多还原

【Abstract】 In order to study the processes of projecting bullet in bore,the numerical simulation 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-DYNA software. The relative velocity curves of the energetic bullets in each layer can be obtained. The simulation results are compared with theoretical estimates. The simulation results can provide a reference for the structure design and damage power calculation.更多还原
