摘　　要：随着巨型星座的加速部署,卫星与卫星之间的碰撞风险急剧增加。为了研究双星碰撞产生的两团碎片云的态势与演化特征,本文模拟计算了双星碰撞产生的两团碎片云的态势与演化,包括碎片云产生后的整体情况、碎片态势情况,讨论了碎片云在位置空间的扩散,包括相关参数的分布特征。研究表明通过倾角矢量和地心惯性系的碎片速度聚类均可有效识别解体碎片的来源母体。研究结果可以为太空交通管理与太空安全防护提供参考建议。With the accelerated deployment of mega constellations,the risk of collisions between satellites has sharply increased.In order to study the situation and evolution characteristics of two debris clouds generated by the collisions of two satellites,this paper simulates and calculates the situation and evolution of the two debris clouds generated by the collisions of two satellites,including the overall situation and debris situation after the generation of the debris clouds,and discusses the dispersion of the debris clouds in positional space,including the distribution characteristics of relevant parameters.Research has shown that both the inclination vector and the velocity clustering of fragments in the geocentric inertial frame can effectively identify the source of disintegrated fragments.The research results can provide reference suggestions for space traffic management and space safety protection.
