Multi-frequency cable vibration experiments
A series of Multi-Frequency cable vibration experiments at Reynolds number 7600 were carried out at the MIT Tow Tank using the Virtual Cable Towing Apparatus (VCTA). Motions observed in a Direct Numerical Simulation of a flexible cylinder in a shear current were imposed on the VCTA and force …

Theoretical and experimental study on cable vibration reduction with a TMD-MR damper
Stay cables are vulnerable to dynamic excitations because of their low intrinsic damping. Excessive cable vibrations cause frequent maintenance and are detrimental to the safety of the entire bridge. Targeting the severe cable vibration problem, in addition to using the existing Magnetorheological …

COMPUTATIONAL FLUID DYNAMICS SIMULATION OF RAIN-WIND-INDUCED VIBRATION OF STAY CABLES
… and severe consequences, the rain-wind induced vibration (RWIV) of stay cables in cable-stayed bridges has been investigated extensively by researchers around the world. However, the underlying excitation mechanism is still unclear. Recently, computational fluid dynamics (CFD) simulation has …

Vibration suppression in finite length marine cable systems
The vibration suppression effectiveness of a flexible in-line marine cable vibration absorber is studied. The transfer matrix method is used to build various numerical models of vibration absorbers in marine cable systems. The models determine cable system natural frequencies, mode shapes and modal …

Investigation of internal damping in carbon fiber and steel cables
The characterization of cable damping is important for the stability and performance of structures deployed in space using cables. However, literature available for the analysis of carbon fiber cable damping and its effect on dynamical behavior of deployable space structure is scarce. The objective …

Estimation of Cable Forces at the Ashton Bridge through Ambient Vibration Testing
… launched to its final position. Hanger cables distribute forces and become more dynamically active as span lengths increase. It is for this reason that the accurate evaluation of forces in the hanger cables is important during construction and for bridge maintenance purposes because they …

Modeling Cable Harness Effects on Space Structures
Due to the high mass ratio of cables on lightweight spacecraft, the dynamic response of cabled structures must be understood and modeled for accurate spacecraft control. Models of cable behavior are reviewed and categorized into three major classes consisting of thin rod models, semi-continuous …
