| 摘 要： | 研究建立宅间碎片对目标超高速撞击条件下临界穿透靶标的损伤特性的理论模型。基于临界穿透过程的数值模拟结果，系统分析了初始条件与临界穿透的关系，捉出碎片临界穿透靶板的比动能概念。然后分析了临界穿透下的碎片比动能，认为比动能是速度的函数。最后，考虑碎片的实际撞击过程巾最大着靶面积为变形面积，对比动能进行修正，获得了极限穿透条件下的真实比动能与速度无关的结论。

| Abstract: | To set up the engineering model of Debris hypervelocity impacting the spacecraft,this paper basing on the SPH simulation of single plate by sphere,Debris Kinetic Energy per unit area is calculated.And giving a result: Debris Kinetic Energy per unit area is function of velocity.At the end,a True Debris Kinetic Energy per unit area is given by using the true sphere area in impacting process.And giving a new result: True Debris Kinetic Energy per unit area is independent on the velocity. |

| Keywords: | Debris Hypervelocity impacting True Debris Kinetic Energy per unit area Orbit spacecraft |
