-
摘要:针对大挠性桁架结构在航天领域的工程应用背景, 对大挠性航天桁架结构进行系统分类, 综述了几种常见的大挠性桁架结构(桁架式空间站/空间承载结构、网状反射天线的支撑结构、环形张紧桁架可展开天线、变几何桁架结构)的研究进展、结构动力学建模进展、主动杆建模进展以及主动控制理论和实验研究进展, 并结合大挠性航天桁架动力学和主动控制的现状, 对这一领域的研究进行展望.Abstract:Large flexiblespace truss (LFST) may be classified according to its applications in spaceindustry. This paper reviews several kinds of LFST (including truss type space station, supporttruss of payload, support truss of mesh reflector antenna, ring tensiontruss, variable geometry truss), their dynamic modeling, active membermodeling, and active control theory and experiment. In the end, some future research topics on dynamic modeling and active control of LFST are pointed out.
