Opto-thermally excited multimode parametric resonance in graphene membranes [PDF]

open access: yesScientific Reports, 2018
In the field of nanomechanics, parametric excitations are of interest since they can greatly enhance sensing capabilities and eliminate cross-talk. Above a certain threshold of the parametric pump, the mechanical resonator can be brought into parametric ...

Analytical solutions of a particular Hill's differential system [PDF]

open access: yesINCAS Bulletin, 2019
Consider a second order differential linear periodic equation. This equation is recast as a first-order homogeneous Hill’s system. For this system we obtain analytical solutions in explicit form. The first solution is a periodic function.

Examination of the virtues of parametric energy coupling in wave energy conversion

open access: yesInternational Marine Energy Journal, 2022
Parametric resonance has been observed, both numerically and experimentally, in various studies of wave energy converters (WECs). Large heave motions induce a periodic variation in the metacentric height of a WEC body and, consequently, cause a harmonic

Simplified Mathieu’s equation with linear friction [PDF]

open access: yesINCAS Bulletin, 2016
Consider a second order differential linear periodic equation. The friction coefficient is real positive constant. Some transformation of the solution and its first derivative allow writing two-order differential equations with void friction coefficients.

Study of the Influence of Nonlinear Moments upon Intensity of Parametric Roll

open access: yesJournal of Marine Science and Engineering, 2022
Hydrodynamical analysis of the conditions for the occurrence of chaotic ship roll, leading in some cases to the capsizing of the vessel, showed that such conditions are most likely to occur in the zone of the main parametric resonance of the roll when ...

Dynamic Analysis on the Parametric Resonance of the Tower–Multicable–Beam Coupled System

open access: yesApplied Sciences, 2022
Considering the effect of the bridge deck’s bending stiffness and the indirect effect of adjacent cables (CEB), this paper aims to propose a refined model to reliably analyze the complex internal resonance mechanism of the tower–multicable–beam coupled ...
