铝球弹丸高速斜撞击铝Whipple防护结构时后板的损伤特性
Damage Characteristics of Rear Walls of Aluminum Whipple Shields by Oblique Hypervelocity Impact of Aluminum Spheres
摘要
Abstract
In order to simulate and study the oblique hypervelocity impacts of space debris on bumper of spacecrafts,a series of oblique hypervelocity impact experiments of aluminum Whipple shields are car- ried out by a two-stage light gas gun. The aluminum alloy projectile diameter is 3.97 mm, the impact velocities range from 1.14 to 5.35 km/s,and the impact angles range from 0° to 70°. The crater distributions on the rear wall of aluminum Whipple shield obliquely impacted by aluminum spheres are obtained and analyzed. In addition, the forecast equations for crater distribution on the rear wall of aluminum Whipple shield by oblique hyperveloeity impact are derived. The results indicate that there are two crater distribution areas on the rear wall under hypervelocity oblique impact. The critical fragmen- tation velocity of projectile will bring effect on the relationship between the impact damage law of rear wall and impact angle. For aluminum alloy Whipple shield,there exists a critical initial collision angle at which the impact damage on the rear wall is the most severe.关键词
