“…Also, the proposed system in this work can be compared to TMDs as it shows the same behaviour and can be utilised as new generation of TMD in real structures in comparison to other carried out studies [ 21 , 22 ]. TMDs and their effectiveness are widely investigated by researchers [ 23 , 24 ] as in the case of severe excitations they can be optimized to suppress the structural vibrations [ 25 – 27 ]. Conversely, the HDM demonstrates more resistant against mistuning in comparison with conventional TMDs [ 28 ].…”

Coulomb friction is considered as a mechanical approach to diminish the structural responses during the excitations. However, in case of severe oscillations supplementary mechanisms are employed besides the friction to mitigate the destructive effects of the vibrations in structures. Therefore, the main goal of this research is to develop a new Hybrid System (HS) which is a parallel combination of Viscous Damping (VD) and Coulomb friction for structures subjected to dynamic load. To achieve this goal, the effect of viscous damper is embedded in the equation of motion which is proposed by Den Hartog for a Single-Degree-of-Freedom (SDOF) Coulomb system, and has been extensively implemented for past few decades. In the considered numerical example in this study, implementing the proposed HDM in system resulted in decreasing the maximum displacement in the range of 1% to 98% for different amounts of force amplitude and viscous damping ratios. Also, applying the proposed HDM increased the time lag for about up to 24% for the frequency ratios greater than 1. The developed hybridized system in this study can be utilised as new generation of Tuned Mass Damper (TMD) to improve their energy dissipating efficiency under severe excitations.

“…To mitigate the limitations of linear dampers, which typically have a narrow vibration suppression frequency band, a series of passive vibration absorbers have been proposed. [1][2][3][4][5] One such absorber is the nonlinear energy sink (NES), a passive vibration suppression device composed of mass, nonlinear stiffness and damping components. [6][7][8][9] NESs have found widespread applications across engineering fields due to their effectiveness in attenuating vibration over a broad frequency range and facilitating targeted energy transfer.…”

Nonlinear energy sink is a passive energy absorption device that surpasses linear dampers, and has gained significant attention in various fields of vibration suppression. This is owing to its capacity to offer high vibration attenuation and robustness across a wide frequency spectrum. Energy harvester is a device employed to convert kinetic energy into usable electric energy. In this paper, we propose an electromagnetic energy harvester enhanced viscoelastic nonlinear energy sink (VNES) to achieve passive vibration suppression and energy harvesting simultaneously. A critical departure from prior studies is the investigation of the stochastic P-bifurcation of the electromechanically coupled VNES system under narrow-band random excitation. Initially, approximate analytical solutions are derived using a combination of multiple-scale method and a perturbation approach. The substantial agreement between theoretical analysis solutions and numerical solutions obtained from Monte Carlo simulation underscores the method’s high degree of validity. Furthermore, the effects of system parameters on system responses are carefully examined. Additionally, we demonstrate that stochastic P-bifurcation can be induced by system parameters, which is further verified by the steady-state density functions of displacement. Lastly, we analyze the impacts of various parameters on mean square current and mean output power, crucial for selecting suitable parameters to enhance energy harvesting performance.
