Experimental characterization of a nonlinear vibration absorber using free vibration
(2016-04-14)
Knowledge of the nonlinear characteristics of a vibration absorber is important if its performance is to be predicted accurately when connected to a host structure. This can be achieved theoretically, but experimental ...
Dynamical behavior and optimization of a nonlinear vibration absorber
(2016-10-01)
The paper concerns the introduction of cubic nonlinearity into a vibration absorber to improve its effectiveness. The nonlinear stiffness is offered by a thin clamped circular plate which undergoes large flexural deflection. ...
Optimization of Axial Vibration Attenuation of Periodic Structure with Nonlinear Stiffness without Addition of Mass
(2020-12-01)
We explore the vibration attenuation of a periodic structure when one absorber with nonlinear cubic stiffness is included without increasing the total mass. Metastructures, and specifically periodic structures, present ...
Nonlinear dynamic vibration absorbers with a saturation
(Elsevier, 2013-03-18)
The behavior of a new type of nonlinear dynamic vibration absorber is studied. A distinctive characteristic of the proposed absorber is the impossibility to extend the system to infinity. The mathematical formulation is ...
Dynamic characteristics of 1 and 2 degrees-of-freedom systems acting as dynamic vibration absorbers on continuum systems
(Asociación Argentina de Mecánica Computacional, 2010-11)
Dynamic vibration absorbers are used to reduce the vibration amplitude of systems near their resonance frequencies. Although its operating principle is easy to understand, its practical use needs some considerations about ...
On vibration mitigation and energy harvesting of a non-ideal system with autoparametric vibration absorber system
(2018-10-01)
This paper demonstrates that vibration mitigation and energy harvesting can be achieved simultaneously by using of an electricity-generating from autoparametric vibration absorber system (AVAS) and non-ideal system (NIS). ...
An investigation into the simultaneous use of a resonator as an energy harvester and a vibration absorber
(Elsevier B.V., 2014-02-28)
A mass-spring-damper system is at the core of both a vibration absorber and a harvester of energy from ambient vibrations. If such a device is attached to a structure that has a high impedance, then it will have very little ...
Vibration attenuation and energy harvesting in metastructures with nonlinear absorbers conserving mass and strain energy
(2022-01-01)
In this work, we explore the performance of vibration attenuation and energy harvesting of a metastructure with vibration absorbers with nonlinear stiffness under harmonic excitation. We devise the metastructure with two ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
