Nonlinear vibrational resonance

Physical Review E, 2013
We examine the nonlinear response of a bistable system driven by a high-frequency force to a low-frequency weak field. It is shown that the rapidly varying temporal oscillation breaks the spatial symmetry of the centrosymmetric potential. This gives rise to a finite nonzero response at the second harmonic of the low-frequency field, which can be ...

Vibrations in a Growing Nonlinear Chain

The interdisciplinary journal of Discontinuity, Nonlinearity, and Complexity, 2021
A one-dimensional chain describing the linear statistical increment of growing homogeneous atoms was arbitrarily built and investigated using an energy potential function. The analytic form of the considered potential has two exponential terms which describes chaotic behavior when the chain was excited.

Nonlinear active vibration damping

IEEE Transactions on Automatic Control, 1994
Summary: A multivariable nonlinear controller is investigated for vibration suppression of flexible structures. The closed-loop gain matrix consists of a varying term added to a constant term. The varying term is proportional to the measured signal, providing rapid cancellation of large deflections and maintaining low noise sensitivity.

Nonlinear Vibrations of a Delaminated Beam

Journal of Vibration and Control, 2001
In this paper, dynamic behavior of a delaminated composite beam is studied. In particular, the effects of nonlinearity due to restriction on the axial stretch of the delaminated segments and nonlinearity due to the deflection-amplitude-dependent axial interaction are studied.

Nonlinear Vibration of Cylindrical Shells

AIAA Journal, 1975
The large amplitude vibrations of a thin-walled cylindrical shell are analyzed using the Donnell's shallow-shell equations. A perturbation method is applied to reduce the nonlinear partial differential equations into a system of linear partial differential equations.

Nonlinear Forced Vibrations of Beams

Journal of Applied Mechanics, 1985
An iterative procedure for computing periodic solutions of nonlinear vibrating beams is presented. The nonlinear partial differential equation is replaced by a coupled system of equations. The contraction mapping principle is then applied to generate a method of successive approximations.

On an Iterative Method for Nonlinear Vibrations

Journal of Applied Mechanics, 1953
Abstract An iterative method for nonlinear vibrations, previously discussed by Brock, is treated from a primarily analytic point of view. In this light, it is a modification of a Picard-like process for two-point boundary conditions mentioned by Gwoh-Fan Djang.

Nonlinear Longitudinal Vibrations of a Rod

Journal of Vibration and Control, 1999
This paper deals with the longitudinal vibrations of a nonlinear rod. The nonlinearity is strong and of cubic type. The motion of the rod is described by a second-order strong nonlinear partial differential equation. The exact numerical solution is obtained.

Vibrational control of a class of nonlinear systems by nonlinear multiplicative vibrations

IEEE Transactions on Automatic Control, 1986
Vibrational control, introduced by \textit{S. M. Meerkov} [ibid. AC-25, 755- 762 (1980; Zbl 0454.93021)], is a nonclassical control principle which proposes a utilization of zero mean parametric excitation of a dynamical system for control purposes.
