摘　　要：为研究航天器外挂设备受到微流星或空间碎片的高速撞击后产生的运动规律和物理现象 ,通过将航天器外挂设备 (太阳能帆板或天线等 )模拟为简单悬挂板 ,得到悬挂板扬角与撞击速度、弹丸直径、材料屈服强度及悬挂板厚度之间的关系曲线 .结果表明在特定条件下悬挂板并非沿着弹丸运动方向上扬而是朝反方向做上扬运动 ,悬挂板朝弹丸运动方向的上扬角是有限的 ,相反其反向扬角在特定条件下无限制增长 .The rules governing the motion of equipment attached to spacecraft under the high-speed impact of micrometers or debris in space were studied. Spacecraft attachment equipment such as solar energy plates and aerials are treated as simple attachment plate to establish the relationship among the elevation of attachment plate, impact speed, diameter of projectile, yield strength of material, and thickness of attachment plate. The results of study indicate that the attachment dose not go up in the direction of projectile under specific conditions and on the contrary it goes up in the opposite direction, but its upward elevation is limited, while its elevation in the opposite direction increases without limits under specific conditions.
