摘要: 航天器铰接结构非线性动力特性研究直接关系到航天器动力学模型的建立、航天器姿态控制方案的制定、有效载荷指向稳定度的保持以及部件可靠性的提高, 是航天器设计领域的研究重点之一. 首先介绍航天器铰接结构研究中发现的非线性动力学现象和对该类问题的研究思路, 然后分别对铰链非线性和高维非线性系统动力学研究的最新研究成果进行介绍, 最后对航天器铰接结构非线性动力学特性研究的发展前景进行总结.Abstract: Non-linear dynamic behaviors of spacecraft joint-dominated structuresare directly related with themodeling, attitude control and pointing precision. This paper brieflyreviews theadvances of studies on local non-linearity, non-linear vibration ofstructures, normal non-linear modes andmodal reduction. And some comments are made about the futuredevelopment in this field.
