摘要
针对现代空间飞行器具有大型挠性附件的特点 ,使用约束模态和非约束模态分别进行求解 ,建立了带挠性附件的空间飞行器的约束模态模型 ,使得对挠性结构的控制成为可能。最后计算了几种情况的约束模态和非约束模态频率 。
Considering flexibility of modern spacecraft,a constrained mode and an unconstrained mode were respectively used to solve this problem in this paper.A model of spacecraft with flexible appendages was built with constrained mode,which enables control of flexibility. Finally,several groups of frequencies of constrained mode and unconstrained mode were computed to verify the accuracy and convenience.
