摘要
某大型卫星经历了长期的地面贮存,从结构生产完成至卫星发射历时9年。文章提取此卫星承力筒、结构板的工程数据,与同类型其他卫星的数据进行对比分析,总结出长期贮存后卫星承力筒和典型结构板——对地板的形变规律,并探讨影响结构变形的原因。研究结果可为后续卫星的贮存设计、贮存试验以及贮存后影响分析提供指导和借鉴。
A large satellite with a long-term ground storage is studied in this paper.It takes nine years from the completion of the structure manufacturing before the satellite launching.Engineering data of the central column shell and the structure panels of this satellite are extracted and then compared with other satellites of the same type.The deformations of typical structures are estimated for satellites with a long-term storage.The factors affecting the deformation of the satellites are analyzed.The results may serve as a guide for the storage design,the storage test and the analysis of the storage influence for the future satellite missions.
