Beam-beam amplitude detuning with forced oscillations [PDF]
Physical Review Accelerators and Beams, 2017 Recently, relations were established between the coefficients of free and forced amplitude detuning polynomial expansions. The forced oscillations were considered only in a single plane.

Nonlinear hybrid-mode resonant forced oscillations of sagged inclined cables at avoidances [PDF]
, 2007 We investigate non-linear forced oscillations of sagged inclined cables under planar 1:1 internal resonance at avoidance. To account for frequency avoidance phenomena and associated hybrid modes actually distinguishing inclined cables from horizontal ...

Investigation of stability in a two-delay model of the ultradian oscillations in glucose-insulin regulation [PDF]
, 2015 In this paper, a two-delay model for the ultradian oscillatory behaviour of the glucose-insulin regulation system is studied. Hill functions are introduced to model nonlinear physiological interactions within this system and ranges on parameters ...

Experimental and numerical studies of inclined cables: free and parametrically-forced vibrations [PDF]
, 2008 Because of few experimental studies in the inclined cable literature, this paper is aimed at experimental modelling and investigating the linear free and nonlinear forced vibrations of sagged inclined cables, by discussing the relevant outcomes in the ...

A numerical study of an inline oscillating cylinder in a free stream [PDF]
, 2011 Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

General Forced Oscillations in a Real Power Grid Integrated with Large Scale Wind Power
Energies, 2016 According to the monitoring of the wide area measurement system, inter-area oscillations happen more and more frequently in a real power grid of China, which are close to the forced oscillation.

On the Countering of Free Vibrations by Forcing: Part II—Damped Oscillations and Decaying Forcing
Applied Mechanics, 2023 The present two-part paper concerns the active vibration suppression for the simplest damped continuous system, namely the transverse oscillations of an elastic string, with constant tension and mass density per unit length and friction force ...

Forced oscillations of beams on elastic bearings
Electronic Journal of Qualitative Theory of Differential Equations, 2004 We study the existence of weak periodic solutions for certain damped and forced linear beam equations resting on semi-linear elastic bearings. Conditions for the periodic forcing term and semi-linear elastic bearings are derived which ensure either the ...

Applied Mechanics, 2022 The question addressed is whether the free oscillations of a continuous system can be suppressed, or at least the total energy reduced, by applying external forces, using as example the linear undamped transverse oscillations of a uniform elastic string.
