Abstract Dynamical and structural systems are susceptible to sudden excitations loadings such as wind gusts, blasts, earthquakes, others which may cause destructive vibration amplitudes lead catastrophic impact on human lives economy. Therefore, various absorbers of linear nonlinear coupling dynamics have been widely studied in plenty publications where some applied real-world practical applications. Firstly, the tuned-mass-damper (TMD), first well-known absorber that has well-studied literature with dynamical systems, is discussed. The TMDs used real-life small- large-scale structures due their robust performance suppression low natural frequency modes. However, TMD performs efficiently at narrowband range its deteriorated by any changes content structure itself. targeted-energy-transfer mechanism found be achieved energy sinks (NESs) ignited interest passive suppression. Unlike TMDs, NESs achieve for wide frequency-energy levels. Given very rapid growth this field extensive research studies supporting robustness NESs, paper presents different types applications main emphasis rotary-based impact-based since they high strong behavior targeted transfer.

Abstract The cubic or third-power (TP) nonlinear energy sink (NES) has been proven to be an effective method for vibration suppression, owing the occurrence of targeted transfer (TET). However, TET is unable triggered by low initial input, and thus TP NES would get failed under low-amplitude vibration. To resolve this issue, a new type with fractional nonlinearity, e.g., one-third-power (OTP) proposed. dynamic behaviors linear oscillator (LO) OTP are investigated numerically, then both feature attenuation performance evaluated. Moreover, analogy circuit established, simulations carried out verify design concept NES. It found that threshold two orders magnitude smaller than parametric analysis shows heavier mass lower stiffness coefficient beneficial in system. Additionally, significant usually accompanied efficient dissipation. Consequently, can realize input energy, which should promising approach micro-vibration suppression.
