Locally Linearized methods for the simulation of stochastic oscillators driven by random forces
(Springer, 2017-03)
In this work, the performance of Locally Linearized integrators for the numerical simulation of stochastic oscillators driven by random forces is studied. This includes the reproduction of a number of dynamical properties ...
The infinitely many zeros of stochastic coupled oscillators driven by random forces
(2017)
In this work, previous results concerning the infinitely many zeros of single stochastic oscillators driven by random forces are extended to the general class of coupled stochastic oscillators. We focus on three main ...
Chaotic oscillation in an attractive Bose-Einstein condensate under an impulsive force
(2002-04-01)
The chaotic oscillation in an attractive Bose-Einstein condensate (BEC) under an impulsive force was discussed using mean-field Gross-Pitaevskii (GP) equation. It was found that sustained chaotic oscillation resulted in a ...
On the critical forcing amplitude of forced nonlinear oscillators
(De Gruyter, 2013-12)
The steady-state response of forced single degree-of-freedom weakly nonlinear oscillators under primary resonance conditions can exhibit saddle-node bifurcations, jump and hysteresis phenomena, if the amplitude of the ...
The topological reconstruction of forced oscillators
(Pergamon-Elsevier Science Ltd, 2009-12)
Periodically forced oscillators are among the simplest dynamical systems capable to display chaos. They can be described by the variables position and velocity, together with the phase of the force. Their phase-space ...
Stability of two-mode internal resonance in a nonlinear oscillator
(Springer, 2018-05)
We analyze the stability of synchronized periodic motion for two coupled oscillators, representing two interacting oscillation modes in a nonlinear vibrating beam. The main oscillation mode is governed by the forced Duffing ...
Forced oscillations with continuum models of atomic force microscopy
(2012-12-01)
The dynamics of the AFM-atomic force microscope follows a model based in a Timoshenko cantilever beam with a tip attached at the free end and acting with the surface of a sample. General boundary conditions arise when the ...
Synchronization of a forced self-sustained Duffing oscillator
(EDP Sciences, 2014-12)
We study the dynamics of a mechanical oscillator with linear and cubic forces – the Duffing oscillator — subject to a feedback mechanism that allows the system to sustain autonomous periodic motion with well-defined amplitude ...
Synchronization properties of self-sustained mechanical oscillators
(Amer Physical Soc, 2013-03)
We study, both analytically and numerically, the dynamics of mechanical oscillators kept in motion by a feedback force, which is generated electronically from a signal produced by the oscillators themselves. This kind of ...
Effects of noise on the internal resonance of a nonlinear oscillator
(Nature Publishing Group, 2018-12)
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self-sustaining force proportional ...
