摘要

摘要: 石英玻璃作为航天器舷窗的重要组成材料，处于航天器的外表面，暴露在空间中，容易遭受空间碎片撞击。为了更好的保障航天器及航天员的安全，对文献[1]中石英玻璃的实验进行数值模拟，并与实验进行比较，发现数值模拟结果与实验结果吻合较好。通过AUTODYN进行数值模拟，得到弹丸直径、弹丸形状、入射速度及入射角度对石英玻璃超高速撞击力学响应的影响。

Abstract: Fused silica glass is important as one of materials that compose space aircraft windows, which is placed on the surface of space aircraft, exposed in outer space and easily subjected to the impact of space debris. Inorder to bet ensurie space aircrafts and astronauts safe better, this paper simulated the impact experiment of fused silica glass in reference [1]. Through the comparison of the numerical simulation result with that of experiments, it was found that they matched well. In AUTODYN, it was obtained that fused silica glass responses to the hypervelocity impact of the ball in different diameters, shapes, incident velocities and incident angles.
