摘要
杆系结构作为航天器的支承结构,已经被广泛地应用于各类天线展开机构中。杆系结构的构型设计对航天器整体构架性能是至关重要的。从能量的观点,采用满应力设计方法,对空间多自由度杆系结构进行了布局优化研究,通过对不同构型优化结果的分析比较,提出了空间杆系结构布局优化原则,对高效率杆系方案的选取和设计具有指导意义。
As a spacecraft＇s support structure,truss has been widely applied to all kinds of mechanisms for deployable antenna.The configuration design of the truss structure is crucial to the spacecraft＇s general performance.From the point of energy,the paper researched the layout optimization of spatial multi-degree of freedom truss structure by the full stress method.Optimization principles were proposed by a comparative study of the optimized structure results under different configuration.This study has certain guiding significance for selecting and designing the high efficiency truss scheme.
