摘要
连接结构广泛用于各种航天器中,这些大量使用的连接结构由于其较低的刚度或非线性特性,会对航天器的动力学特性产生显著的影响。本文简要介绍了与在轨航天器连接结构动力学问题有关的以下问题:航天器中所使用连接结构的动力学模型及其参数辨识问题,连接结构对航天器结构动特性的影响,含连接结构动力学系统的周期解、分叉和混沌。
The presence of joints can strongly affect the dynamics of spaceraft,especially if the joints are numerous,of low stiffness,or nonlinear.This paper presents an overview of the recent advances in dynamics and parameter identification of joints in spacecraft.Several problems are discussed including different kinds of joint structure,dynamic models of these joints,dynamic characteristics of spacecraft affected by joints,and parameter identification of joints.Further more,the periodic response analysis,bifurcation and chaos of dynamic system including joints are presented too.
