Nonlinear Energy Sinks With Piecewise-Linear Nonlinearities

AL-Shudeifat, Mohammad A.·2019·Journal of Computational and Nonlinear Dynamics

Abstract

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 of the symmetric clearance, the NES is coupled to the linear structure by either linear or nonlinear stiffness elements. The damping is assumed to be continuous linear viscous damping during the oscillation of the NES mass inside and outside the clearance zone. This design is further modified by incorporating a negative coupling stiffness within the clearance zone. Therefore, the performance of the proposed piecewise NESs in rapid vibration suppression is numerically investigated with two-degree-of-freedom spring-mass system and compared with existing NESs in the literature. Accordingly, significant improvement in vibration suppression has been achieved by the proposed piecewise NES compared with other types of existing NESs. Moreover, the numerical simulation results have shown more robustness in the piecewise NES performance for a wide range of stiffness and damping variations than the linear absorber and other types of NESs in the literature.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • NESs with clearance nonlinearities are coupled to the primary structure through non-smooth piecewise nonlinearities with optimizable clearances and stiffness characteristics.

    “This type of NES is coupled to the primary structure through non-smooth piecewise nonlinearities with optimizable clearances and stiffness characteristics.”
  • The targeted energy transfer mechanism by the piecewise NES was verified on the frequency energy plot via multiple strong resonance captures on the in phase and out of phase backbone curves.

    “Consequently, the TET mechanism by the piecewise NES was verified on the FEP via multiple strong resonance captures on the in phase and out of phase backbone curves.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
