An analogue twin for piezoelectric vibration damping of multiple nonlinear resonances
Autor: Gaëtan Kerschen, Jean-François Deü, Boris Lossouarn
Publikováno v: Journal of Sound and Vibration
Journal of Sound and Vibration, Elsevier, 2021, 511, pp.116323. ⟨10.1016/j.jsv.2021.116323⟩
The objective of this study is to extend the concept of analogous piezoelectric networks to vibration mitigation of multiple nonlinear resonances. First, the undamped linear part of the electrical network is designed so as to possess similar modal ch

Journal of Sound and Vibration, Elsevier, 2021, 496, pp.115921. ⟨10.1016/j.jsv.2020.115921⟩
Marine lifting surfaces may undergo flow-induced vibrations due to fluid sources of excitation, leading to shorter life cycles due to structural fatigue and critical to the acoustic performances (e.g hydrofoil singing). As such, accurate understandin

Modal-based synthesis of passive electrical networks for multimodal piezoelectric damping
Autor: Ghislain Raze, Jennifer Dietrich, Boris Lossouarn, Gaëtan Kerschen
This work presents a new approach to design an electrical network which, when coupled to a structure through an array of piezoelectric transducers, provides multimodal vibration mitigation. The characteristics of the network are specified in terms of
