title = "A study of damage AL-mesh bumper by hypervelocity impact of AL-spheres",
abstract = "In order to study the hypervelocity impact of space debris on spacecraft through hypervelocity impact on 5052 aluminum mesh bumper, a two-stage light gas gun was used to launch 2017-T4 aluminum alloy sphere projectiles. The diameter of projectiles was 4mm. Impact velocities of AL-spheres were varied between 3.5km/s and 5km/s. The fragmentation and dispersal of hypervelocity particle against mesh bumper varying with mesh specification were analyzed. The protection performance of AL-mesh bumper against hypervelocity projectiles impact was assessed. Hypervelocity normal impact debris distribution of mesh bumper was investigated by numerical simulation. The influence of different impact point on morphology of debris clouds was obtained. The results indicated that the main factors affecting the protection ability of mesh bumper from hypervelocity impact are the arrangements of mesh wall and mesh specification. Cross point of mesh can help enhancing the performance of shields.",
