摘要
近年来大口径空间光学望远镜以高像质、宽波段、大幅宽等特点,在开展空间科学探索、精细化对地观测等方面越来越重要。大口径望远镜的主承力结构、大型光学组件的支撑结构往往采用桁架结构,本文围绕实现桁架结构的超轻、超稳特性,从构型优化设计、新型材料、先进制造工艺、精确测量标定方法等方面,系统性梳理了其理论基础、研究方法、应用现状等,并探讨了空间桁架结构技术的发展趋势。
In recent years,large⁃aperture space optical telescope has become more and more important in space scientific exploration and fine earth observation because of its high image quality,wide band and wide range.The main bearing structure of large⁃aperture telescope and the supporting structure of large optical components often use truss structure.Focusing on the realization of the ultra light and ultra stable characteristics of truss structure,this paper systematically combs its theoretical basis,research methods and application status from the aspects of configuration optimization design,new materials,advanced manufacturing technology and accurate measurement and calibration methods,and discusses the development trend of space truss structure technology.
