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.

非线性能量汇综述:冲击式和旋转式的设计、分析和应用
动力和结构系统容易受到突然的激励和载荷的影响,例如阵风、爆炸、地震和其他可能导致破坏性振动幅度并对人类生活和经济造成灾难性影响的因素。因此,各种线性和非线性耦合动力学的减振器已在大量出版物中得到广泛研究,其中一些已应用于现实世界的实际应用中。首先,讨论了调谐质量阻尼器 (TMD),这是第一个著名的线性减振器,已在文献中得到充分研究,并应用于各种结构和动力系统。TMD 等线性减振器因其在低固有频率结构模式的振动抑制方面的稳健性能而广泛应用于现实生活中的小型和大型结构。然而,TMD 在窄带频率范围内有效执行,在窄带频率范围内,其性能会因结构中频率内容和 TMD 本身的任何变化而恶化。因此,通过非线性能量汇 (NES) 实现的目标能量传递机制激发了人们对被动非线性振动抑制的兴趣。与 TMD 不同,NES 是动态吸振器,可实现宽范围频率能量水平的振动抑制。鉴于该领域的快速增长以及支持 NES 稳健性的广泛研究,
