High-damping rubber (HDR) dampers have the advantages of convenience for various shapes pressure blocks, aesthetic installation, easy maintenance, temperature stability, etc.; thus, they present good application prospects in vibration reduction stay cables. Hence, a model taut cable equipped with two types HDR damper—i.e., damper and tuned mass–high-damping (TM-HDR-D)—is established herein. The...

To study the complex mechanism of high-dimensional nonlinear cable systems, a 3 degree-of-freedom model reduced from tower-cable-beam structure is proposed and investigated in this paper. Based on D’Alembert Principle, dynamic equations in-plane out-of-plane vibration are established simulated by 4th-order Runge-Kutta method. The results exhibit phenomenon coupling internal resonance under syst...

Based upon a framework of time-frequency analysis, a path towards systematic and comprehensive implementation of condition based maintenance (CBM), or maintenance only upon evidence of need, is outlined for both electrical and mechanical systems. Specifically, metrics are proposed for helicopter drivetrain systems and electrical cable. Using principles of time-frequency analysis, metrics for he...

Cable-suspended parallel robot (CPR), in which cables are utilized to replace links to manipulate objects, is developed from parallel and serial cable-driven robot. Compared with the parallel robot, this kind of robot has more advantages. The cooperative variation of lengths of six cables pulls the feed cabin to track radio source with six degrees of freedom (DOFs). Similar to a parallel robot,...

It is essential to construct structural health monitoring systems for large important bridges. Zhijiang Bridge is a cable-stayed bridge that was built recently over the Hangzhou Qiantang River (the largest river in Zhejiang Province). The length of Zhijiang Bridge is 478 m, which comprises an arched twin-tower space and a twin-cable plane structure. As an example, the present study describes th...
