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.
Keywords:ccable system  dynamics  control  modeling
