Abstract

This research aims to investigate the effect of top end excitation on the dynamic responses of a mooring cable, which is installed in a floating photovoltaic system. The mathematical model formulation of the elastic cable is developed based on the principle of virtual work. The nonlinear static configurations of cables are evaluated by using the nonlinear finite element procedure. The Newmark’s time integration is applied to determine the dynamic responses of a mooring cable due to the harmonic top end excitation. The constraint conditions of the top end excitation are imposed in the equation of motions by using the penalty method. According to the top end sway and heave excitation, the effects of amplitude and frequency of the top end excitation on the dynamic responses of cable are investigated.
