Nonlinear oscillations of cables under harmonic loading using analytical and finite element models.
The authors study nonlinear interaction phenomena in cable dynamics. To this end, they use analytical and finite element models. The study achieved two results: the well-established analytical procedure generally used to determine asymptotic solutions and their stability makes it possible to validate the ability of the finite element numerical procedure to follow complex scenarios, albeit limited to stable oscillations; at the same time, the richer finite element model represents a possibility to verify both the hypotheses assumed in the derivation of the analytical model and the suitable dimensions of the reduced discrete model. The authors also investigate the response under in- and out-of-plane loading in a large frequency range, giving a complete description of the response under harmonic excitation.
