摘　　要： 采用非火药驱动二级轻气炮发射球形铝质弹丸，对铝双层板结构进行高速撞击实验研究，从而模拟空间碎片对航天器防护结构的高速撞击作用．实验得到了该铝双层板结构的前后板在不同速度区间的高速撞击损伤模式．获得了弹丸撞击速度在0．5—5．0km／s时该铝双层板结构的撞击极限曲线，并与Christiansen方程的预测撞击极限曲线进行比较，同时分析了后板材料的屈服强度对铝双层板结构高速撞击防护性能的影响. In order to simulate and study the high-velocity impact of space debris on Aluminum dual-wall structure of spacecrafts, a non-powder two-stage light gas gun was used to launch M-sphere projectiles. Damage mode of bumper and back wall of aluminum dual-wall structure at different impact velocity ranges were obtained. Ballistic limit carve of aluminum dual-wail structure with impact velocity between 0. 5 km/s and 5.0 km/s were obtained, which were compared with predicted curve from Christiansen Ballistic limit equation. And the effect of yield strength of back wall material on resist capability of aluminum dual-wall structure by hypervelocity impact was analyzed.
