“…The structure is characterized by the stiffness and damping which can be considered to be either the cubic Duffing, cubic-quintic Duffing or Rayleigh, or another such as the Van der Pol with first, second, third, fourth and fifth term. The stiffness is expressed as a sum of a linear and a cubic Duffing term, while the damping is considered to be linear (See [6]).…”

In this work, analysis of the response to vibrations of a small building equipped with an electromechanical vibration absorber is investigated. The case of harmonic excitation with constant or time dependent frequencies is considered. The interaction between the structure and the energy source is analyzed via the Sommerfeld effect inside the resonance region. The resonance capture and the vibration reduction are displayed by the time history displacement of the last story.

“…It was concluded that when the unsteady wind is present, IPD decreases the amplitude of galloping in all cases of loading, but has no influence on the galloping onset. Notice that the IPD can be introduced via a damper device in the interfloors damping as reported in [13]. Its use as a control strategy was motivated by its simple implementation and beneficial effect in reducing vibration in many engineering applications.…”

This paper investigates the influence of combined fast external excitation and fast parametric damping on the amplitude and the onset of galloping of a tower submitted to steady and unsteady wind flow. A lumped single degree of freedom model is considered and the cases where the turbulent wind activates either external ex-citation, parametric one or both are studied. The methods of direct partition of motion and the multiple scales are used to drive a slow dynamic near primary resonance. The influence of the combined excitations on the galloping is examined showing the beneficial effect on the amplitude and the onset of galloping when the excitations are introduced together.

“…The energy source is influenced by the response of the system and consequently, the system exhibits jumps at critical values of the energy source. The system mimics a disappearance of the energy in the resonance regions which can affect the stability of the system, sending it to chaos [2][3][4].…”

The paper discusses the chaotic behavior of a vibrating structure coupled to an energy source. The structural response of this system may act like energy sink under certain conditions so that a part of the energy supplied by the source is spend to vibrate the structure rather than increasing the drive speed, according to the Sommerfeld effect [1]. The energy source is influenced by the response of the system and consequently, the system exhibits jumps at critical values of the energy source. The system mimics a disappearance of the energy in the resonance regions which can affect the stability of the system, sending it to chaos [2][3][4].
