A nonlinear electromechanical pendulum arm with a Nonlinear Energy Sink control (NES) approach
(2016-01-01)
This paper considers the nonlinear dynamics of an electromechanical device with a pendulum arm and a Nonlinear Energy Sink (NES) put on the point of the pendulum suspension. It is shown that the (NES) is capable of absorbing ...
On an Active Control for a Structurally Nonlinear Mechanical System, Taking Into Account an Energy Pumping
(Asme-amer Soc Mechanical Eng, 2009-07-01)
The purpose of this work is to investigate the control of the oscillations and the suppression of vibrations in damped and coupled oscillators. In this sense, we look into the potential of using a nonlinear energy sink in ...
Comments on energy harvesting on a 2:1 internal resonance portal frame support structure, using a nonlinear-energy sink as a passive controller
(2016-01-01)
This paper presents an application of a passive control strategy in a base-excited two-degrees-of-freedom portal frame support structure considering extract energy using a piezoelectric material coupled to a column. The ...
Numerical study of a symmetric single-sided vibro-impact nonlinear energy sink for rapid response reduction of a cantilever beam
(2020-04-01)
This paper concerns an investigation into the control of the transient vibration of an Euler–Bernoulli beam using a symmetric single-sided vibro-impact nonlinear energy sink (SSSVI NES). The non-dimensional system of ...
On an energy exchange process and appearance of chaos in a non-ideal portal frame dynamical system
(2013)
In this paper, we consider non-ideal excitation devices such as DC motors with restrictenergy output capacity. When such motors are attached to structures which needexcitation power levels similar to the source power ...
Numerical Study of a Single-Sided Vibro-Impact Track Nonlinear Energy Sink Considering Horizontal and Vertical Dynamics
(Asme, 2019-12-01)
In this paper, the single-sided vibro-impact track nonlinear energy sink (SSVI track NES) is studied. The SSVI track NES, which is attached to a primary structure, has nonlinear behavior caused by the NES mass moving on a ...
Application of passive control to energy harvester efficiency using a nonideal portal frame structural support system
(Sage Publications Ltd, 2014-03-01)
An analysis of a new energy harvester model is presented, based on a simple portal frame structure, considered a nonideal system due to the kind of excitation influenced by the response of the system, such as a direct ...
On elimination of chaotic behavior in a non-ideal portal frame structural system, using both passive and active controls
(2013-04-01)
In this paper, an application is considered of both active and passive controls, to suppression of chaotic behavior of a simple portal frame, under the excitation of an unbalanced DC motor, with limited power supply ...
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 ...
On energy pumping, synchronization and beat phenomenon in a nonideal structure coupled to an essentially nonlinear oscillator
(Springer, 2009-04-01)
In this paper, we dealt with energy pumping, synchronization, and beat phenomenon in transients and steady-state vibrations (in a non-ideal structure (NIS)) having an attachment, coupled to an oscillator containing essential ...
