Forced vibration resonators and free vibration of the hull
International Shipbuilding Progress, 1971As ships increase in size, the formulas previously used to describe ships' vibrations are being found to contain errors which are leading to expensive repairs and lost time. The article describes the various differences between the previous calculations used and the vibrations which are actually being found to occur.

Analysis of vibrational resonance in a quintic oscillator
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2009We consider a damped quintic oscillator with double-well and triple-well potentials driven by both low-frequency force f cos ωt and high-frequency force g cos Ωt with Ω⪢ω and analyze the occurrence of vibrational resonance. The response consists of a slow motion with frequency ω and a fast motion with frequency Ω.

Resonance in piezoelectric vibrators
Proceedings of the IEEE, 1970The electrical behavior of a piezoelectric vibrator leads to criteria by which to describe onset and extent of the resonance region. The equi-immittance point is convenient for delimiting the resonance range and assesses the validity of circle representations. A list of characteristic frequencies is given with determining equations.

Resonant and Near-Resonant Vibrational—Vibrational Energy Transfer between Molecules in Collisions
The Journal of Chemical Physics, 1964A semiclassical calculation of the probabilities of resonant and near-resonant vibrational energy interchange in molecular collisions is accomplished by means of a collision model similar to that used in vibrational—translational energy transfer. The results indicate that transition probabilities are of the order of ½ in resonant and near-resonant ...

Energy Harvesting Enhancement by Vibrational Resonance
International Journal of Bifurcation and Chaos, 2014The idea to use environmental energy to power electronic portable devices is becoming very popular in recent years. In fact, the possibility of not relying only on batteries can provide devices longer operating periods in a fully sustainable way. Vibrational kinetic energy is a reliable and widespread environmental energy, that makes it a suitable ...

Novel vibrational resonance in multistable systems
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2011We investigate the role of multistable states on the occurrence of vibrational resonance in a periodic potential system driven by both a low-frequency and a high-frequency periodic force in both underdamped and overdamped limits. In both cases, when the amplitude of the high-frequency force is varied, the response amplitude at the low-frequency ...

Vibrational resonance in excitable neuronal systems
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2011In this paper, we investigate the effect of a high-frequency driving on the dynamical response of excitable neuronal systems to a subthreshold low-frequency signal by numerical simulation. We demonstrate the occurrence of vibrational resonance in spatially extended neuronal networks.

Parametric vibrations and resonance
2003Summary: We examine a system of linear differential equations with periodic coefficients depending on parameters. For small changing parameters, the monodromy matrix and eigenvalues are constructed. We consider the problem of stability of trivial solution of the damped Hill equation and obtain the domains of stability in the parameter space.
