Phase resonance nonlinear modes of mechanical systems
Martin Volvert, Gaetan Kerschen
The resonances of forced dynamical systems occur when either the amplitude of the frequency response undergoes a local maximum (amplitude resonance) or phase lag quadrature takes p…
optimization of multiple tuned mass dampers for multimodal vibration control
Ghislain Raze, Gaetan Kerschen
In this paper, a new computational method for the purpose of multimodal vibration mitigation using multiple tuned mass dampers is proposed. Classically, the minimization of the max…
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…
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…
