空间带电粒子辐照效应的地面加速试验研究

Study for Ground Accelerated Test of Space Radiation Effect

空间带电粒子辐照下空间材料的损伤与失效是空间材料学研究的重要组成内容,地面模拟加速试验是研究材料辐照损伤效应的重要方法和技术途径。文章阐述了地面辐照加速试验的方法及相关概念,以光学石英玻璃为例验证辐照加速试验与模拟等效区间的概念,为当前研究材料在空间带电粒子辐照环境条件下的行为与航天器设计、选材提供科学依据。

Under the space charged particle radiation, the damage and failure is the important content in the investigation of space material science, and ground accelerated test is the important study method and technology for radiation damage on materials. In the paper, the methods and related concepts in ground accelerated test are introduced, and the optical quartz glass is set as an example to demonstrate radiation accelerated test and simulation equivalent range. The studies about ground accelerated test will help to provide the scientific criteria for materials behavior, spacecraft design and materials selection under space charged particle radiation.
