摘　　要：为研究间隙对穿孔装甲抗弹性能的影响,应用ANSYS/LS-DYNA仿真计算方法对高速弹丸垂直侵彻穿孔装甲钢板孔边缘进行数值模拟,从弹丸对不同间隙后效靶垂直深度、弹体剩余速度等方面进行分析研究,结果表明在一定范围内,间隙的增大可提高多孔钢板的抗弹性能,为装甲防护设计提供重要依据。The numerical simulation of high-speed projectile vertically penetrating the hole edge of perforated armor plate is Carried out by the method of ANSYS/LS-DYNA simulation in order to research the influence of intervals on the ballistic per- formance of perforated armor. The study of vertical penetration depth, residual velocity of projectile shows that the increase of space value can improve the ballistic performance of perforated target within a certain range, which provides significant basis for the design of armor protection.
