| 摘 要： | 文章为了分析超高速弹丸对Whipple防护结构后墙的撞击损伤，利用质量守恒、动量守恒及能量守恒等分析了碎片云运动特性，在此基础上构造了碎片云对Whipple防护结构后墙的法向撞击载荷函数，为进一步分析弹丸超高速正撞击Whipple防护结构后其后墙的裂纹长度提供了有效的分析工具。

| Abstract: | In order to analyze the impact damage,a motion model of debris cloud is developed to characterize its motion based on the conservation laws for mass,momentum and energy.Then a function of normall impact load on spacecraft wall is constructed on the basis of this debris cloud motion model,which provides an effective tool for further analyzing hole diameter and crack length for Whipple shield under normal HVI. |
