“…Zhang et al 37 found that at the beginning of the wing vibration, because the initial position was not in the balance position, the energy generated by the primary system vibration was immediately absorbed and dissipated by the NES. The vibration was temporarily suppressed and the instantaneous resonance capture occurred.…”

“…The TET technique of the NES was applied to the research of vibration reduction in civil engineering and it was pointed out that the TET phenomenon could occur under 1:2 and 1:3 resonances besides 1:1 internal resonance. Zhang et al 37 studied the vibration response mechanism of the two-dimensional wing with the NES under different inflow velocities. The results showed that the frequency range of the TET could be widened when the NES was installed on the both side of the wing and the critical inflow velocity threshold could be increased when using the NES to effectively suppress the wing vibration.…”

In recent years, the research of nonlinear energy sink on low-frequency noise control has become a hotspot. By adding a nonlinear energy sink into one primary system, it is possible to obtain the significant target energy transfer characteristics. The target energy transfer can be defined for which the vibration energy of the primary structure is irreversibly transferred to the nonlinear energy sink, quickly concentrated in the nonlinear energy sink and dissipated by the nonlinear energy sink damping. This method has significant advantages to control the broadband low-frequency noise inside the transportations (such as cars, trains, airplanes, etc.). Compared with traditional noise reduction methods such as adding the damping and acoustical materials, the nonlinear energy sink has a simple and lightweight structure. The paper reviews the nonlinear characteristics of the nonlinear energy sink, the main theoretical research methods and the applications of vibration and noise control, and discusses the application of the nonlinear energy sink for the control of low-frequency noise inside the three-dimensional acoustic cavities, which provides the reference and guidance for the low-frequency noise control inside the acoustic cavities of the mean of transportation.

“…It is important to emphasize that the simplified airfoil model does not completely reflect the real situation, but it is commonly used for the studies of aeroelasticity problems in different areas, such as aircraft wing, [1][2][3][4][5][6][7][8][9] aeroengine turbine blades, 10 and others. A series of research results on conceptual airfoil models have been reported, including bifurcation and stability analysis, flutter control, [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] airfoil-based energy harvesting, [55][56][57][58][59][60] etc. Meanwhile, the latest review articles have been given a comprehensive overview on the recent advances of typical aeroelastic airfoil and panel structures.…”

During the past few decades, several significant progresses have been made in exploring complex nonlinear dynamics and vibration suppression of conceptual aeroelastic airfoil models. Additionally, some new challenges have arisen. To the best of the author’s knowledge, most studies are concerned with the deterministic case; however, the effects of stochasticity encountered in practical flight environments on the nonlinear dynamical behaviors of the airfoil systems are neglected. Crucially, coupling interaction of the structure nonlinearities and uncertainty fluctuations can lead to some difficulties on the airfoil models, including accurate modeling, response solving, and vibration suppression. At the same time, most of the existing studies depend mainly on a mathematical model established by physical mechanisms. Unfortunately, it is challenging and even impossible to obtain an accurate physical model of the complex wing structure in engineering practice. The emergence of data science and machine learning provides new opportunities for understanding the aeroelastic airfoil systems from the data-driven point of view, such as data-driven modeling, prediction, and control from the recorded data. Nevertheless, relevant data-driven problems of the aeroelastic airfoil systems are not addressed well up to now. This survey contributes to conducting a comprehensive overview of recent developments toward understanding complex dynamical behaviors and vibration suppression, especially for stochastic dynamics, early warning, and data-driven problems, of the conceptual two-dimensional airfoil models with different structural nonlinearities. The results on the airfoil models are summarized and discussed. Besides, several potential development directions that are worth further exploration are also highlighted.

“…Yan et al [27] evaluated the usability of the NES in controlling the nonlinear transonic flutter of a 2D wing aeroelastic system and showed that the NES may shift the wing flutter system to a new equilibrium position, in terms of the mean oscillation. Zhang et al [28] studied the airflow-induced vibration of a 2D wing coupled with two nonlinear energy sinks in a free stream and analyzed the relationship between vibration suppression and targeted energy transfer.…”

A nonlinear energy sink (NES) is used to suppress panel flutter. A nonlinear aeroelastic model for a two-dimensional flat panel with an NES in supersonic flow is established using the Galerkin method. First-order piston aerodynamic theory is adopted to build the aerodynamic load. The effects of NES parameters on flutter boundaries of the panel are investigated using Lyapunov’s indirect method. The mechanism of the NES suppression of panel flutter is studied through energy analysis. Effects of NES parameters on aeroelastic responses of the panel are obtained, and a design technique is adopted to find a suitable combination of parameter values of the NES that suppresses the panel flutter effectively. Results show that the NES can increase or reduce the onset dynamic pressure of the panel flutter and it can reduce the aeroelastic response amplitude effectively within a certain range of dynamic pressure behind the onset dynamic pressure. The installation position of the NES depends on the direction of the airflow. The robust characteristics should be considered to find the suitable combination of parameter values of the NES.
