摘要：
In this paper, the performance of linear passive vibration absorbers and nonlinear passive vibration absorbers or nonlinear energy sink (NES) on the stability properties and nonlinear behaviors of an aeroelastic model is investigated. For this purpose, an airfoil model subjected to quasi-steady aerodynamics flow is considered. The results show that the linear absorbers with parameters identical to the NES lead to better stability characteristics and nonlinear behaviors in comparison with NES, and with optimizing the values of the linear absorber's parameters, they perform appropriately in comparison with both single and multi-degree of freedom NESs. This performance is also observed in the nonlinear characteristics of responses such as limit cycle oscillation.
