Abstract: This paper is devoted to study and compare dynamics of primary linear oscillator (LO) coupled to cubic and vibroimpact (VI) nonlinear energy sink (NES) under transient and periodic forcing. The classic analytical procedure ...

Abstract: In this paper, the dynamic response of a harmonically forced linear oscillator (LO) strongly coupled to a nonlinear energy sink (NES) is investigated both theoretically and experimentally. The system studied comprises an ...

Abstract: Recent works have studied ground resonance in helicopters under the aging or damage effects. Indeed, blade leadlag stiffness may vary randomly with time and differ from blade to blade. The influence of stiffness dissimilarities ...

Abstract: Recently, it has been demonstrated that a vibroimpact type nonlinear energy sink (VINES) can be used efficiently to mitigate vibration of a linear oscillator (LO) under transient loading. The objective of this paper is to ...

Abstract: The objective of this paper is to demonstrate the motion reconstruction and the parameter estimation of a vibro-impact (VI) system from limited experimental information. Based on the measured displacement and acceleration ...
