“…4. NES with inerter [135][136][137][138][139][140]: In the inerter NES, the NES mass is either replaced by an inerter or accompanied with it to achieve a significant reduction in the NES mass which maintains or improves the optimized efficiency of vibration suppression [135,136]. The NES mass in [137] is kept and attached to an inerter of small mass fraction of the original linear system.…”

“…When the inerter mass is equal to the NES mass, the vibration response of the structure has been considerably reduced compared to the case of using the NES without inerter. In recent studies, the inerter NES has been further investigated with a suspension system by using a quasi-zero stiffness in [138], by using an asymmetric nonlinear energy sink in [139] and for suppressing torsional vibration in [140]. 5.…”

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

“…This kind of absorber with strong nonlinearity is called a nonlinear energy sink (NES) (Ding and Chen, 2020). At present, the NES has been used in the vibration mitigation of suspension systems (Zeng et al, 2020), airfoil systems (Fasihi et al, 2021), and pipes conveying fluid (TZ Yang et al, 2014).…”

Although a linear vibration absorber (LVA) or nonlinear energy sink (NES) can effectively mitigate the vibration of a primary system in harmonic excitation, the amplitude of the absorber can be very large. Using the differential evolution algorithm, this paper pioneers the global control of the primary system and absorber to achieve decent vibration mitigation and decrease the global response. The results show that the maximum amplitude of the primary system and absorber can be controlled at the same level, and the global control strategy does not change the resonance frequency of the primary system. Compared with the LVA, the NES has similar vibration mitigation effects, mass ratio, and damping values. However, different from the LVA, the NES can achieve optimal mitigation effects in multiple optimal combinations of spring stiffness and geometry parameter and have smaller frequency responses in large excitation. Therefore, this paper proves the superiority of the NES in global vibration control.

“…The equation of motion of the pipe system with dry friction is derived through the generalized Hamilton's principle. From a perspective of vibration control [25][26][27][28][29], by taking advantage of the energy-consumption characteristic of the dry friction, the dry friction is also expected to be effective at adjusting/controlling the stability and dynamics of the system of pipes conveying fluid.…”

A cantilevered pipe conveying fluid can lose stability via flutter when the flow velocity becomes sufficiently high. In this paper, a dry friction restraint is introduced for the first time, to evaluate the possibility of improving the stability of cantilevered pipes conveying fluid. First, a dynamical model of the cantilevered pipe system with dry friction is established based on the generalized Hamilton’s principle. Then the Galerkin method is utilized to discretize the model of the pipe and to obtain the nonlinear dynamic responses of the pipe. Finally, by changing the values of the friction force and the installation position of the dry friction restraint, the effect of dry friction parameters on the flutter instability of the pipe is evaluated. The results show that the critical flow velocity of the pipe increases with the increment of the friction force. Installing a dry friction restraint near the middle of the pipe can significantly improve the stability of the pipe system. The vibration of the pipe can also be suppressed to some extent by setting reasonable dry friction parameters.
