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 ...
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. ...
A note on non-linear phenomena in a non-ideal oscillator, with a snap-through truss absorber, including parameter uncertainties
(2013-03-01)
This work considers the vibrating system that consists of a snap-through truss absorber coupled to an oscillator under excitation of an electric motor with an eccentricity and limited power, characterizing a non-ideal ...

Heat loss of a trapezoidal cavity absorber for a linear Fresnel reflecting solar concentrator
(Pergamon-Elsevier Science Ltd, 2012-03)
The present paper studies the heat loss of a linear absorber with a trapezoidal cavity and a set of pipes used for a linear Fresnel reflecting solar concentrator. The study includes the measurements on a 1.4 m long prototype ...
Uso de absorvedores de vibrações eletromecânicos lineares e não-lineares em sistemas não-lineares e não-ideais

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 ...
