摘　　要：针对厘米/毫米级非金属碎片对典型空间目标的撞击风险评估,在基于AUTODYN有限元分析软件计算非金属碎片对3种典型结构的撞击毁伤特性基础上,结合毁伤树分析法建立了一种典型空间目标易损性分析方法,介绍了该易损性分析方法的总体思路和各项关键技术,获得了典型空间目标在非金属碎片撞击下导致不同毁伤等级的系统失效概率,并给出了典型空间目标的应用实例。结果表明:所提出的易损性分析方法可用于无人航天器在遭受厘米/毫米级空间非金属碎片撞击后的系统失效影响分析。To study the impact risk assessment of centimeter/millimeter level non-metallic debris on typical space targets,a typical space target vulnerability analysis method was estab-lished based on the damage characteristics of three typical structures hit by non-metallic debris ca-culated by AUTODYN finite element analysis software and the damage tree analysis method.First,the general idea and key technologies of the proposed vulnerability analysis method were introduced.Then,the system failure probability of typical space targets under non-metallic debris impacts leading to different damage levels was obtained.Furthermore,applications of the pro-posed method on typical space targets were given.Research results indicated that the proposed method could be used for system failure study of satellites and other unmanned spacecrafts hit by centimeter/millimeter level non-metallic debris.
