“…A similar pattern and a demonstrated rule exist for the case of Nonlinear Energy Sink (NES) and vibro-impact dampers, see e.g. in [64][65][66][67], where the optimal damping is shown to be for two impacts per periods. Nevertheless, the case considered here is slightly different and needs further study to elaborate a proof.…”

“…Note that these findings agree very well with the existing documents related to NESs. For example, the evidence of SMR for highly efficient TET could be broadly found in various types of NES systems under forced vibrations, and the importance of SMR and VI-2 responses for a conventional VINES to realize TET is also reported by many other authors, see [42][43][44][45]. Especially, in [17,37], it is also proved that SMR and VI-2 are the most important two regimes for TET in EM-VINES under harmonically forced vibrations.…”

An electromagnetic vibro-impact nonlinear energy sink (EM-VINES) is proposed in the application of vortex-induced vibration (VIV), for both purpose of vibration suppression and energy harvesting. The considered system consists of a cylinder-like bluff body subject to an oncoming flow, coupled to a magnet attachment moving in coil of gap enclosure. The fluidstructure interaction is treated using the classical Van der Pol oscillator model, and the non-smooth dynamics is formulated in a measure differential complementarity problem adapted with a Moreau-Jean time integration scheme. Comprehensive analyses are then conducted concerning the targeted energy transfer mechanism, as well as the internal competition of the energy flow. A performance indicator is defined over the lock-in region, to obtain the optimal balance between vibration suppression and energy harvesting. It is found that when the system is working in a strongly modulated regime with less than 2 impacts per cycle, a fast-scale targeted energy transfer could be activated over the whole lock-

“…An important research avenue is the field of nonlinear vibration mitigation. Several solutions, such as nonlinear energy sinks, 6,7 autoparametric vibration absorbers, 8,9 nonlinear tuned vibration absorbers, 10,11 friction devices, 12,13 and impact dampers [14][15][16] have demonstrated beneficial strengths over traditional linear solutions. Another, more recent trend consists in adding nonlinear elements to a nonlinear structure in order to prescribe its characteristics, for instance, by linearizing its global behavior.…”

This work proposes a novel efficient method to track the evolution of amplitude extrema featured by frequency responses of nonlinear systems using the harmonic balance method. Means to compute the amplitude of a Fourier series are first outlined, and a set of equations characterizing a local extremum of a nonlinear frequency response amplitude curve is derived. Efficient numerical procedures are used to evaluate these equations and their derivatives (including second‐order ones) to embed them in a predictor‐corrector continuation framework. The proposed approach is illustrated on three examples of increasing complexity, namely a Helmholtz–Duffing oscillator, a two‐degree‐of‐freedom system with a modal interaction, and a doubly clamped von Kàrmàn beam with a nonlinear tuned vibration absorber.
