Abstract:

The transverse resonant vibration of stranded wire rope was studied as part of an overall investigation of flow-induced cable vibrations. It was found that an equivalent homogeneous string model adequately predicts the cable resonant frequencies. Furthermore, the in-water damping and added mass exhibit no dependence on amplitude, mode shape, or wavelength, and the frequency dependence is slight. The measured damping and added mass were combined to form a stability parameter which can be used to correctly estimate the maximum amplitude of the transverse vibrations induced by the interaction between a steady current and an elastic or elastically-mounted structure.
