| 摘 要： | 在建立数学物理模型的基础上,对低地球轨道环境和地面试验环境下有无保护涂层的聚酰亚胺所受原子氧冲蚀及紫外线的综合作用进行了数值模拟,获得了具有工程应用价值的计算结果,并讨论了数学物理模型中各参数对基蚀曲线形状的影响.从数值模拟结果与美国太空试验结果的比较可以看出,得出的数值模拟的结果是正确的,对航天器设计具有重要的指导意义. |

| Abstract: | Based on a mathematical mode proposed by the authors to describe the physical interactions of atomic oxygen and ultraviolet with polyimide, numerical simulations of their combined radiation effects on polyimide with and without coated layers in Low Earth Orbit (LEO) and ground experiment environment were conducted. The results are consistent with the Long Duration Exposure Facility (LDEF) results, providing a valuable reference for the design of spacecrafts. |
| Keywords: | oxygen atoms ultraviolet radiation numerical simulation spacecraft lifetimes polyimide |
