空间飞行器碎片防护结构的简化设计

Simplified Design Method for the Spacecraft Shield Structure

给出一种基于实验和理论分析的航天器碎片防护结构简化设计方法 ,该方法可用于进行大型空间飞行器碎片防护结构的方案选择和初步结构设计。利用空间碎片的工程环境模型和防护结构几何经验公式 ,采用“设计碎片”的概念 ,对防护结构进行几何结构设计和质量估算 ,并采用改进的防护性能验证算法进行空间碎片的风险评估。通过对惠式防护结构的计算 ,得到的计算结果基本符合实际要求。

Based on the experiments and theoretical analysis, a simplified spacecraft shield design method is developed in this paper, to choose the shield style and begin the preliminary spacecraft shield design A supposed metal particle is produced as the 'design' particle to equate the effect made by realized debris The semi-empirical geometrical formulation for specific shield and the orbital debris engineering environment model are also utilized to roughly size the bumper and rear wall of meteoroid/debris shields The results of Whipple Shielding are consistent with that of other methods, so this design method developed is efficient and applied for the realized engineering design work.
