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. ...
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 ...
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 ...
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 ...
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 ...
Active vibration control using delayed resonant feedback
(2013-09-01)
Delayed feedback (DF) control is a well-established technique to suppress single frequency vibration of a non-minimum phase system. Modal control is also a well-established technique to control multiple vibration modes of ...
The non-ideal problem behavior using a dynamic vibration absorber with nonlinear essential stiffness and timedependent damping properties
(2013-03-01)
The purpose of this study is to develop a dynamic vibration absorber using viscoelastic material with nonlinear essential stiffness and time-dependent damping properties for a non-ideal vibrating system with Sommerfeld ...
Robust broadband vibration control of a flexible structure using an electrical dynamic absorber
(Iop Publishing Ltd, 2011-07-01)
This paper presents a simple but practical feedback control method to suppress the vibration of a flexible structure in the frequency range between 10 Hz and 1 kHz. A dynamic vibration absorber is designed for this, which ...
Influence of temperature on optimum viscoelastic absorbers in cubic nonlinear systems
(Sage Publications Ltd, 2014-11)
Recently, viscoelastic materials have been widely used for vibration control due to their efficacy and flexibility in real engineering problems. Their use as constitutive parts of dynamic vibration absorbers requires the ...
On a Nonideal (MRD) Damper-Electro-mechanical Absorber Dynamics
(World Scientific Publ Co Pte Ltd, 2011-10-01)
In this paper, we have investigated the nonlinear dynamic behavior of an electro-mechanical vibration absorber (NEVA), taking into account a modified (MR) Damper (MRD), in its mathematical model, which was excited by a ...
