玻璃钢空间碎片防护构型性能的实验研究与仿真分析

Experimental and analytical studies of the performance of FRP protective configuration against space debris

  • 摘要: 在不增加空间碎片防护构型体积、质量的约束条件下提升防护构型的性能,一直是空间碎片防护领域的一项重要工作。文章设计了玻璃钢填充层结构与玻璃钢铝板贴合后壁结构2种防护构型,通过开展弹道靶超高速碰撞实验和数值仿真分析,探究这2种玻璃钢防护构型与等面密度Whipple构型的防护性能差异。实验中采用铝弹丸直径为4.0 mm,碰撞速度范围为4.64~4.80 km/s,同时使用Autodyn软件开展数值仿真进行补充论证。结果表明:玻璃钢铝板贴合后壁构型相对于传统的Whipple屏防护性能更好,玻璃钢填充层构型比玻璃钢铝板贴合后壁构型的防护性能更优;同时仿真分析显示,冲击波在后壁内反复振荡的构型可能具有更好的防护效果。

     

    Abstract: For the space debris protection, it is always important to develop structures with good protection performance without increasing the volume or the mass of the protective configuration. In this paper, two kinds of protective configurations are designed. One contains a filled layer structure with another using the FRP-Al plate as the rear wall. By carrying out the hypervelocity impact test within the ballistic range, the differences of the protective capabilities among the two kinds of protective configurations and the Whipple structure of the same surface density are investigated. The diameter of the projectile is 4.0 mm, and the impact velocity is adjusted between 4.64 km/s and 4.8 km/s. Meanwhile, the numerical simulation is carried out by the Autodyne software. It is shown that the configuration using the FRP-Al plate as the rear wall performs better than the traditional Whipple shield, and the structure using the FRP plate as the filled layer performs even better. The preliminary conclusion can be drawn from the Autodyn simulation that the configuration tends to induce a shock wave oscillating in the rear wall, which may lead to a better protective capability.
