Abstract

This paper presents an estimation method for assessing the damage to the rear wall of spacecraft protective structures caused by hypervelocity impacts of space debris. Utilizing the smoothed particle hydrodynamics for numerical simulation, a kernel-function based kinetic energy mapping method is employed to analyze the kinetic energy distribution of the debris cloud generated by the initial impact upon the rear wall. This study establishes a correlation between the kinetic energy of the debris cloud and the resulting damage to the rear wall. This correlation allows for the estimation of damage characteristics, including the depth and volume of impact craters on the rear wall following exposure to a debris cloud. Taking the hypervelocity impacts of an Al-2017 projectile on an Al-6061 thin plate as examples, experimental validation has demonstrated the effectiveness, robustness and versatility of this method over a range of particle sizes and grid resolutions. This method enables rapid estimation of damage to protective structures and assessment of their residual protective performance.

超高速碰撞下航天器防护结构损伤估计方法

提出了空间碎片超高速撞击对航天器防护结构后壁损伤的估计方法。利用光滑粒子流体力学进行数值模拟，采用基于核函数的动能映射方法，分析了初始撞击后壁面产生的碎片云的动能分布。本研究建立了碎片云的动能与对后壁造成的损伤之间的相关性。这种相关性可以用来估计损伤特征，包括暴露于碎片云后后壁上的撞击坑的深度和体积。以Al-2017弹丸对Al-6061薄板的超高速撞击为例，实验验证了该方法在不同粒径和网格分辨率下的有效性、鲁棒性和通用性。该方法能够快速估计防护结构的损伤并评估其剩余防护性能。
