【摘要】 在实验数据分析的基础上,详细分析导弹燃料舱的几何结构和易损性,建立了燃料舱的物理模型和有限元模型,应用AYSYS/LS-DYNA三维有限元程序仿真计算了高速弹丸对导弹燃料舱的侵彻毁伤过程。计算结果表明,选择合适的材料模型能够再现高速弹丸对导弹燃料箱的侵彻全过程。更多还原

【Abstract】 The geometry structure and damage characteristics were analyzed detailed on foundation of analyzing experimential data,and the physical models and the finited element models of fuel cabin were established.The invasion and damage process of high-speed pill damaged cruise missile’s fuel cabin was simulated and calculated with ANSY/LS-DYNA.Simulation is well tallied with experiment,it proved that the whole process of high-speed to invade missile’s fuel cabin can be reappearanced with appropriate material models.更多还原
