Planar non-linear free vibrations of an elastic cable
TL;DR: In this paper, a non-linear equation of the free motion of a heavy elastic cable about a deformed initial configuration is developed, which is obtained via a Galerkin procedure, an approximate solution is pursued through a perturbation method.
Analytical and numerical approaches to nonlinear galloping of internally resonant suspended cables
TL;DR: In this article, a model of a curved cable-beam, geometrically nonlinear and able to torque, was used to account for quasi-steady aerodynamic forces, including the effect of static swing of the cable and dynamic twist of the cross-section.

Non-linear galloping of sagged cables in 1:2 internal resonance
Angelo Luongo,Giuseppe Piccardo +1 more
TL;DR: In this article, the aeroelastic behavior of a flexible elastic suspended cable driven by mean wind speed, blowing perpendicularly to the cable's plane, is investigated by applying the Galerkin procedure to the partial differential equations of motion and using an in-plane and an out-ofplane mode as shape functions.

Linear instability mechanisms for coupled translational galloping
Angelo Luongo,Giuseppe Piccardo +1 more
TL;DR: In this article, a linearized coupled flexural two degree-of-freedom model, describing a lumped parameter system subjected to galloping, is analyzed and an approximated analytical solution for the eigenvalue problem is determined.

Dynamic analysis of externally excited NES-controlled systems via a mixed Multiple Scale/Harmonic Balance algorithm
Angelo Luongo,Daniele Zulli +1 more
TL;DR: In this paper, a general, nonlinear, multi-d.o.f. structure, excited by harmonic external force in 1:1 resonance with one of the modes of the system, is considered.
