“…In the literature, several terms are used for such devices: dynamic vibration absorber (DVA), tuned mass damper (TMD) or inertial damper. Numerous types of non-linear absorbers are in use today (Ocak et al, 2022). Among them are: pendulum-like absorbers, torsional absorbers, absorbers with quasi-zero or negative stiffness, vibro-impact dampers and many others.…”

In this article, we study dynamical behaviour of a 2-DOF mechanical system subjected to an external harmonic force. This system which consists of the Duffing oscillator considered as a bulk system and a linear dynamic vibration absorber (LDVA) attached to it. An analytical approach for optimal choice of the parameters of the LDVA is suggested with the aim to avoid the "superfluous" increase in the amplitude of forced oscillations of the main system. The analysis performed shows that when using a linear absorber, its proper tuning (choice of stiffness and damping coefficients) gives satisfactory results -the peak values of the frequency-amplitude curve (FAC) are decreasing comparatively with the case of the linear main oscillator.

“…Traditional passive controllers usually use linear or nonlinear dampers, such as viscous dampers, friction dampers, and viscoelastic dampers [7,8]. These dampers can effectively dissipate the vibration energy of the structure and thus reduce the displacement and acceleration response of the building structure.…”

Currently, the application of electromagnetic dampers in structural vibration control and energy harvesting has become increasingly widespread. The optimization research of electromagnetic dampers in building design has also received more attention. Previous studies on vibration control of building structures with electromagnetic dampers have been conducted under fixed foundations, neglecting the effect of soil-structure interaction on building structures with electromagnetic dampers. The main contribution of this paper is to fill the research gap in the study of building structural vibration control with electromagnetic dampers considering soil-structure interaction. An effective design and parameter optimization method for building structures with both soil-structure interaction and electromagnetic energy harvesting is explored. The soil-structure interaction is taken into account, and the building model with electromagnetic dampers is improved to form a coupled vibration reduction system with both structural vibration control and energy harvesting functions. The dynamic equations of the system with both structural vibration control and energy harvesting are derived and then optimized using the H2 norm criterion and Monte Carlo-mode search method. A single-layer building structure is used as an example to study the influence of soil-structure interaction on building structures equipped with electromagnetic dampers under strong earthquake action. The dynamic response and energy harvesting of building structures under earthquake action considering soil-structure interaction are analyzed and evaluated. The results show that the influence of soil-structure interaction on building structures equipped with electromagnetic dampers needs to be considered. As the soil density decreases, the dynamic response of the building structure under earthquake action becomes larger using the electromagnetic damper system. Compared to the use of fixed foundations, the energy harvesting effect of building structures with electromagnetic dampers is weakened when considering soil-structure interactions.

“…Therefore, developing new strategies for protecting building structures from damage caused by disasters has become a very important research topic [1,2]. In recent years, several control methods have been proposed to reduce structural vibrations in civil engineering structures, such as active [3,4], semi-active [5], passive [6,7], and hybrid vibration control [8]. Among them, passive control has been broadly used [9,10].…”

Viscoelastic (VE) dampers show good performance in dissipating energy, being widely used for reducing vibration in engineering structures caused by earthquakes and winds. Experimental studies have shown that ambient temperature has great influence on the mechanical behavior of VE dampers. Therefore, it is important to accurately model VE dampers considering the effect of temperature. In this paper, a new fractional-order Zener (AEF-Zener) model of VE dampers is proposed. Firstly, the important influence of fractional orders on the energy dissipation ability of materials is analyzed. Secondly, an equivalent AEF-Zener model is developed that incorporates the ambient temperature and fractional-order equivalence principle. Finally, the chaotic fractional-order particle swarm optimization (CFOPSO) algorithm is used to determine the model’s parameters. The accuracy of the AEF-Zener model is verified by comparing model simulations with experimental results. This study is helpful for designing and analyzing vibration reduction techniques for civil structures with VE dampers under the influence of temperature.
