【摘要】 绳索系统具有无限自由度,当计入非线性因素的作用时,其面内和面外的振动相互耦合,呈现非常丰富的非线性动力学行为.另外,绳索系统经常工作在风、流体、微重力、电磁力等作用下,进一步加剧了其动力学的复杂性.绳索系统的动力学现象引起了工程界和力学界的关注.本文对绳索在重要工程系统中的应用及相应的动力学现象进行概述,给出了柔索的动力学建模过程,对绳索系统的动力学和控制研究进行了总结,并指出了值得进一步关注的若干问题.更多还原

【Abstract】 Elastic cables have been frequently used in various engineering fields, such as civil engineering, space engineering, electric and communication engineering. In general, the mechanical model of a cable includes an infinite number of degrees of freedom. The geometric nonlinearity in the cable movement usually makes the in-plane and out-of-plane vibrations coupled with each other so that the cable dynamics may exhibit abundant nonlinear phenomena. Furthermore, a cable system is often subjected to the external excitations such as wind, rain, fluid, micro-gravity and alternative electro-magnetic fields, which definitely enhance the complexity of the cable dynamics. Therefore, the cable dynamics has drawn much attention over the past decades. After a, brief introduction to some typical applications of cables and related dynamics, this review presents the methods of dynamic modeling of cable systems, surveys the recent advances in dynamics analysis and vibration control for cable systems, and points out a few open problems to that should pay more attention.更多还原
