碎片云靶板分布及其在模型验证中的应用

为评价碎片云对星内电子仪器设备的毁伤特性，提出了靶板分布的概念，并给出了相应的定义。作为靶板分布的一个应用，针对Swift碎片云模型导出了粒子在靶板上的位置，求出了靶板上粒子的分布函数、密度函数以及密度函数的极值点。通过与大量实验得到的碎片云粒子在靶板上分布的比较，证明了Swift碎片云模型的分布与实验结果不符,不能正确反映碎片云的碰撞特性。

Distribution of debris cloud in impacted sheet and its application in model validation

In order to assess the damage characteristics of the debris cloud to the electronic apparatus and equipment inside the satellite, a concept about the distribution in impacted sheet is proposed, and the relevant definition is presented in this paper. Taking Swift’s model of the debris cloud as an application example, this paper gives the position of the debris cloud particle, the distribution function, the density function and its extremums. A comparison of the density functions between Swift’s model and large numbers of experiments shows that the Swift’s debris cloud model is not in accord with the experiments, and thus cannot reveal impact characteristics of the debris cloud correctly.
