    Abstract
  • All spacecraft in low orbit are subjected to hypervelocity impacts by meteoroids and space debris, which can lead to significant damage and catastrophic failure. Investigation into the impact damage characteristics has become an important problem for spacecraft protection designing. In this paper, by experiment and numerical simulation of hypervelocity impact on thin Al-plate by Al-spheres, and it is found that AUTODYN-2D SPH is an effective method of predicting penetration hole diameter in thin Al-plates from hypervelocity impact. By numerical simulation of projectile diameter, projectile velocity and thin Al-plate thickness effect on penetration hole diameter in thin Al-plates from hypervelocity impact, and fitting curves with experiment and simulation results, the law of penetration hole diameter and leading factors affecting penetration hole diameter in thin Al-plates from hypervelocity impact was proposed.
