Method for Evaluating Shielding Thicknesses and Radiation Dose Inside Spacecraft Based on ProE

为准确评估结构异常复杂的航天器内部遭遇的辐射剂量,本文将直线近似原理和ProE工程软件相结合,自主开发了一种新型的航天器三维屏蔽与辐射剂量评估方法。利用本方法对立方体、球、平板等简单几何体内部的屏蔽厚度和辐射剂量进行了分析计算,计算结果表明基于ProE的三维屏蔽与辐射剂量计算方法是可靠的。结构复杂程度相当于中等规模航天器的模型计算结果表明,本方法能够较高效的分析评估复杂航天器内部遭遇的屏蔽厚度和辐射剂量。

In order to compute the Total Ionization Dose(TID) in a complex spacecraft accurately,a novel method for evaluating the radiation dose inside the spacecraft is proposed in this paper by integrating the straight line theory with the software Pro/ENGINEER.Shielding thicknesses and radiation doses in several simple geometry bodies such as cubic,sphere,planar,etc are computed by the method respectively.The results indicate that the new method based on software Pro/ENGINEER is credible.What's more,a complex model equivalent to the middle scale spacecraft is computed,the result indicates that the new method based on the software Pro/ENGINEER is highly effective.
