Isolated resonances and nonlinear damping
Giuseppe Habib, Giuseppe Ilario Cirillo, Gaetan Kerschen
We analyze isolated resonance curves (IRCs) in a single-degree-of-freedom system with nonlinear damping. The adopted procedure exploits singularity theory in conjunction with the h…
A principle of similarity for nonlinear vibration absorbers
Giuseppe Habib, Gaetan Kerschen
This paper develops a principle of similarity for the design of a nonlinear absorber, the nonlinear tuned vibration absorber (NLTVA), attached to a nonlinear primary system. Specif…
Identification of Nonlinear Normal Modes of Engineering Structures under Broadband Forcing
J. P. Noël, L. Renson, C. Grappasonni +1
The objective of the present paper is to develop a two-step methodology integrating system identification and numerical continuation for the experimental extraction of nonlinear no…
The harmonic balance method for bifurcation analysis of large-scale nonlinear mechanical systems
Thibaut Detroux, Ludovic Renson, Luc Masset +1
The harmonic balance (HB) method is widely used in the literature for analyzing the periodic solutions of nonlinear mechanical systems. The objective of this paper is to exploit th…
Performance, robustness and sensitivity analysis of the nonlinear tuned vibration absorber
Thibaut Detroux, Giuseppe Habib, Luc Masset +1
The nonlinear tuned vibration absorber (NLTVA) is a recently-developed nonlinear absorber which generalizes Den Hartog's equal peak method to nonlinear systems. If the purposeful i…
Suppression of Limit Cycle Oscillations using the Nonlinear Tuned Vibration Absorber
Giuseppe Habib, Gaetan Kerschen
The objective of the present study is to mitigate, or even completely eliminate, the limit cycle oscillations in mechanical systems using a passive nonlinear absorber, termed the n…
