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 connection structure is widely used in a variety of spacecraft. These heavily used connection structures have a significant impact on the dynamics of the spacecraft because of their low stiffness or non-linearity. In this paper, we briefly introduce the following issues related to the dynamics of on-orbit spacecraft joint structure: the dynamics model of the joint structure used in the spacecraft and its parameter identification, the influence of the joint structure on the dynamic characteristics of the spacecraft structure, Periodic Solution of Dynamic System, Bifurcation and Chaos.
