...Collin Treacy; Dalton Stein; David Chelidze Efficient passive vibration absorption can prevent the failure of systems without requiring sensors or energy sources. Nonlinear energy sinks (NES) have gained popularity as passive vibration absorbers due to their targeted energy transfer (TET...

..., at high levels, can lead to failure of the systems. This work proposes an investigation of electromagnetic-enhanced nonlinear energy sinks (NES-EH) for the hybrid mitigation of aeroelastic LCOs and energy harvesting. The study focuses on a prismatic bluff body with a linear suspension immersed...

...Yong Wang; Tao Zhang; Xianyu Jin; Yin Yin Shimmy motion may occur for an aircraft nose landing gear (NLG) during its takeoff, landing, and taxiing procedure, which is an undesirable motion and should be suppressed. Here, a novel torsional nonlinear energy sink (NES) based on the cam-roller...

...Qingchao Yang; Shuang Li; Zhaozhao Ma Nonlinear energy sink (NES) systems, when applied to a physical system with multiple interference sources, exhibit abundant nonlinear dynamic behaviors. However, current research in this respect is limited within the theoretical scope of deterministic systems...

...Lisha Zhu; Cong Yuan; Guo Yao; Huanjun Li; Wei Gao In this paper, a nonlinear energy sink (NES) is designed and applied for the suppression of the friction-induced vibration (FIV) of a braking system. The equation of motion of the braking system, as well as the NES, is established by using...

...Mohammad A. Al-Shudeifat; Adnan S. Saeed The frequency-energy plots (FEPs) of two-degree-of-freedom linear structures attached to a piecewise nonlinear energy sink (PNES) are generated here and thoroughly investigated. This study provides the FEP analysis of such systems for further understanding...

...Mohammad A. AL-Shudeifat An efficient nonlinear energy sink (NES) is developed here by employing a symmetric piecewise nonlinear coupling force. The proposed piecewise NES has a symmetric clearance about its equilibrium position in which zero stiffness is assumed. However, at the boundaries...

...S. N. J. Costa; J. M. Balthazar The purpose of this work is to investigate the control of the oscillations and the suppression of vibrations in damped and coupled oscillators. In this sense, we look into the potential of using a nonlinear energy sink in combination with an optimal linear control...
