Strumming of nonlinear cable elements using modal superposition
AbstractA wake-oscillator model of cable strumming effects is used in a numerical procedure to predict the strumming response of hydrodynamically loaded cable systems incorporating long curved cables. The finite element method is used in a combined time-domain and frequency-domain solution method. Transverse strumming motions are assumed to be small compared to nonlinear in-line displacements and to occur at much higher frequencies than the in-line frequencies. A modal superposition technique is used to predict strumming response superposed on nonlinear time-domain solutions for in-line motions. Two examples are included, a horizontal cable vibrating in a uniform current, and a three-leg single point mooring of a large buot subject to ocean waves.
