摘　　要：该文结合某型陶瓷复合装甲的侵彻实验,利用三维非线性动力有限元程序LSDYNA3D,建立高速钨质长杆弹对多层陶瓷复合装甲侵彻的有限元分析模型,描述了侵彻全过程的有关物理和力学现象,并与实验进行对比,数值结果与实验结果吻合,对进一步研究复合装甲防护及弹体侵彻性能具有一定的参考价值。With respect to an actual experiment, finite element simulation using LS-DYNA3D is performed to investigate the responce of a ceramic integral armor penetrated by high-velocity long rod of tungsten alloy. The main penetrating patterns are obtained and discussed. The simulateel results are in good agreement with the experimental results. It gives useful insight into the investigations on the protective composite systems and rod projectiles.
