对在轨航天器撞击解体问题进行了研究,基于NASA标准解体模型,给出了在轨航天器撞击解体算法,重点分析了解体计算时应该满足的几个约束条件.编写了该算法的通用仿真计算程序,并通过与P-78卫星解体事件的实测数据比较验证了算法和程序的正确性.研究结果对预测分析在轨撞击事件的毁伤特性具有重要的参考价值.

The collision breakup problem of orbital spacecraft is studied in this paper. The collision breakup algorithm of orbital spacecraft is presented based on NASA standard breakup model. Constraint conditions required for the breakup calculation are analyzed emphatically. Finally, the general utility simulation calculation program is implemented, and is verified to be correct by comparing with measured data of P-78 satellite breakup event. The research can be an important reference to predict and analyze damage characteristics of orbital collision events.
