Journal ArticleDOI
New breathing functions for the transverse breathing crack of the cracked rotor system: Approach for critical and subcritical harmonic analysis
TL;DR: In this article, two new breathing functions were identified to represent the actual breathing effect on the cracked element stiffness matrix, which were then used in formulating the time-varying finite element stiffness matrices of a cracked element.
Journal ArticleDOI
Highly efficient nonlinear energy sink
TL;DR: In this article, the performance of the nonlinear energy sink (NES) that composed of a small mass and essentially nonlinear coupling stiffness with a linear structure is considerably enhanced by including the negative linear and nonlinear stiffness components.
Journal ArticleDOI
Numerical and experimental investigation of a highly effective single-sided vibro-impact non-linear energy sink for shock mitigation
Mohammad A. AL-Shudeifat,Nicholas E. Wierschem,D. Dane Quinn,Alexander F. Vakakis,Lawrence A. Bergman,Billie F. Spencer +5 more
TL;DR: In this article, a single-sided vibro-impact (VI) attachment with highly asymmetric impact nonlinearity (the VI NES) is proposed to absorb and rapidly dissipate a considerable amount of the impulse energy induced into the linear structure.
Journal ArticleDOI
Resonance captures and targeted energy transfers in an inertially-coupled rotational nonlinear energy sink
Grigori Sigalov,Oleg Gendelman,Mohammad A. AL-Shudeifat,Leonid I. Manevitch,Alexander F. Vakakis,Lawrence A. Bergman +5 more
TL;DR: In this article, the authors explore the conservative and dissipative dynamics of a two-degree-of-freedom (2-DoF) system consisting of a linear oscillator and a lightweight nonlinear rotator inertially coupled to it.
Journal ArticleDOI
General harmonic balance solution of a cracked rotor-bearing-disk system for harmonic and sub-harmonic analysis: Analytical and experimental approach
TL;DR: In this paper, the effect of crack depth on vibration amplitudes and whirl orbit shapes is investigated through a general harmonic balance technique and experimental verification, and it is shown that the unique signature of orbits for the breathing crack model can be used as an indication of a breathing crack in the shaft.
