Measurements of the Hydrodynamic Force and Strum Characteristics of Stranded Cables

Abstract

The Naval Coastal Systems Center performed a series of cable tests in the high-speed tow basin at the David Taylor Naval Ship Research and Development Center. Steady and unsteady lift and drag characteristics and strum responses were measured for five twisted wire ropes. Fourteen-foot cable models were tensioned between two struts and towed over a velocity range of 2 to 10 knots with yaw angles varying from 20 to 90 degrees. From the mean steady force data, lift and drag loading functions were developed for each cable. The force and strum characteristics of the cables were compared with results from previous tests of circular cylinders and cable sat yaw angles. Keywords: Hydrodynamic forces; Measurement; Stranded cables; Drag measurement; Wire rope; Lift; Towed cables, Cables.
