Flow-Induced Vibrations of Taut Marine Cables with Attached Masses.
Abstract
A series of cable strumming field experiments were conducted at Castine Bay, Maine. The test site, instrumentation, cable, and experimental procedures are described in detail. The purpose of this test series was to provide an accurate data base for the validation of the computer code NATFREQ which was developed at the California Institute of Technology for the Naval Civil Engineering Laboratory to predict the natural frequencies and mode shapes for taut cable systems subjected to flow-induced vibration. In addition, the drag amplification model developed at the Naval Research Laboratory has been included in the NATFREQ code for the prediction of amplified drag coefficients for strumming cables. The predicted natural frequencies and drag coefficients obtained from a NATFREQ analysis of the Castine Bay Experimental series were compared to the measured values. Good correlation between the predicted and measured values has been obtained. A detailed description of these comparisons and the NATFREO code is provided.
