摘　　要：为明晰弹着点位置的变化对多孔钢板抗弹性能影响的趋势,应用ANSYS/LS-DYNA分析技术,对多孔钢板在15°法线角抗14.5 mm穿燃弹侵彻进行数值模拟,取得弹着点位置不同时14.5 mm穿燃弹对后效靶的侵彻深度。结果表明,孔中心的防护能力最弱,孔边缘右侧及3孔之间防护能力最强。In order to know the influence of the varied hitting positions on the ballistic performance of multi-hole steel plate, numerical simulation of the multi-hole steel plate protecting against 14.5 AP with normal angle of 15 degrees, which is based on ANSYS-DYNA analysis technique was carried out. Different penetrating depths of 14.5 AP hitting on varied positions were obtained. The results of the experiments show that center of the hole has the minimum ballistic performance, while the area near the right rim of the hole and among the three holes has the maximum ballistic performance.
