摘要
以惠普尔 ( Whipple)防护屏结构为例 ,通过实验研究了铝合金柱状弹体以第一门槛值附近的速度正撞击 LY1 2合金防护屏的特点 ;研究了不同速度下防护屏损伤随速度的变化规律 ;对于速度在第一门槛值附近的速度正撞击 ,得到了撞击速度、防护屏及靶体厚度。
Characteristic of the normal impact of cylindrical projectile onto LY12 aluminum Whipple shielding Concept within the first doorsill value are studied with an example of dual-sheet Whipple structure through experimental investigation.So,shielding Concept damage behaviors with projectile velocity are presented.Within the first doorsill value of normal impact,the change of velocity,thickness of shielding and target,prevention distance can deeply affect the results of shielding ang target.
