Forced Vibrations of a Nonhomogeneous String

SIAM Journal on Mathematical Analysis, 2008
We prove existence of vibrations of a nonhomogeneous string under a nonlinear time periodic forcing term in the case in which the forcing frequency avoids resonances with the vibration modes of the string (nonresonant case). The proof relies on a Lyapunov–Schmidt reduction and a Nash–Moser iteration scheme.

ON THE FORCED VIBRATION TEST BY VIBRODYNE

Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015
In civil engineering, Experimental Modal Analysis (EMA) dynamic tests are powerful aids to the seismic design of new structures, and useful tools for the structural identification of existing structures. EMA tests require to accurately evaluate the harmonic forcing function that is applied to the structure under testing, in order to correctly apply ...

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.

Forced vibrations of a beam with a non-linear dynamic vibration absorber

Journal of Sound and Vibration, 1983
Abstract Forced vibrations of a simply supported beam having an attached non-linear dynamic vibration absorber and excited by sinusoidal motion of its supporting base are investigated analytically. The absorber produces a hardening spring force in the form of a cubic curve. The governing partial differential equation reduces to the well-known Duffing
