摘要
轨道空间高能粒子辐射环境是航天器材料和器件损伤或性能退化的重要影响因素,威胁航天器在轨安全可靠运行。空间辐射环境复杂,为尽可能真实地模拟空间辐射环境效应,在地面等效试验具有较高的可信度。本文针对抗辐射性能地面等效试验环境参数确定问题,提出基于自适应广义层次期望提高的等效试验设计方法,并以Kapton薄膜为例,进行抗辐射性能地面模拟等效试验设计,验证了本文提出的等效试验设计方法的有效性。
In this paper,a generalized hierarchical expected improvement equivalent experiment(GHEIEE)method is proposed based on adaptive generalized hierarchical expectation improvement,which is used to determine the environmental parameters of ground equivalent experiments for radiation resistance performance.By using the SPENVIS software,ground simulation equivalent test parameters are searched for the spatial radiation effect of Kapton thin films,and compared with equivalent test schemes in literature to further validate the effectiveness of the proposed method and provide theoretical assistance for subsequent research on spacecraft radiation equivalent test design.
