Identification of Secondary Resonances of Nonlinear Systems using Phase-Locked Loop Testing
Tong Zhou, Gaetan Kerschen
One unique feature of nonlinear dynamical systems is the existence of superharmonic and subharmonic resonances in addition to primary resonances. In this study, an effective vibrat…
MEMS-EYE: A M/NEMS platform for the investigation of multi-physical and complex nonlinear systems
Samer Houri, Gaetan Kerschen
The ultimate goal of this research proposal is the creation of a micro-optomechanical intelligence. The proposal centers on the development and investigation of very large-scale in…
Onset and stabilization of delay-induced instabilities in piezoelectric digital vibration absorbers
Ghislain Raze, Jennifer Dietrich, Gaëtan Kerschen
The stability of a piezoelectric structure controlled by a digital vibration absorber emulating a shunt circuit is investigated in this work. The formalism of feedback control theo…
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…
