“…Attention was also paid to the conception of the individual electronic components in order to improve the performance of the control boards. Numerical and experimental studies have led to the design of a synthetic inductor also useful for multi-modal applications, [14], as well as the possibility of optimizing the number of components used in order to streamline the circuit assembly complexity, [15]. The effect of changing positions of piezo patches along the analyzed structure are discussed in [16].…”

This paper deals with the issue of developing a smart vibration control platform following an innovative model-based approach. As a matter of fact, obtaining accurate information on system response in pre-design and design phases may reduce both computational and experimental efforts. From this perspective, a multi-degree-of-freedom (MDOF) electro-mechanical coupled system has been numerically schematized implementing a finite element formulation: a robust simulation tool integrating finite element model (FEM) features with Simulink® capabilities has been developed. Piezo strain actuation has been modelled with a 2D finite element description: the effects exerted on the structure (converse effect) have been applied as lumped loads at the piezo nodes interface. The sensing (direct effect) has instead been modelled with a 2D piezoelectric constitutive equation and experimentally validated as well. The theoretical study led to the practical development of an integrated circuit which allowed for assessing the vibration control performance. The analysis of critical parameters, description of integrated numerical models, and a discussion of experimental results are addressed step by step to get a global overview of the engineering process. The single mode control has been experimentally validated for a simple benchmark like an aluminum cantilevered beam. The piezo sensor-actuator collocated couple has been placed according to an optimization process based on the maximum stored electrical energy. Finally, a good level of correlation has been observed between the forecasting model and the experimental application: the frequency analysis allowed for characterizing the piezo couple behavior even far from the resonance peak.

“…Edberg et al (1991) added a second branch to a classical series RL shunt to mitigate two resonances, and this circuit was later generalized to an arbitrary number of modes by Hollkamp (1994). A number of other topologies were proposed since then, such as the current blocking shunt (Agneni et al, 2006;Wu, 1998), the current flowing shunt (Behrens et al, 2003), the seriesparallel impedance structure (Fleming et al, 2003), and a Cauer-type network (Goldstein, 2011). Each of these circuits proved rather difficult to tune, and numerical optimization was often needed for circuits with known (Cigada et al, 2012;Fleming et al, 2002;Gardonio et al, 2019) or unknown (Berardengo et al, 2017;Dal Bo et al, 2022) topology.…”

This work presents tuning rules for piezoelectric shunts aiming to mitigate multiple structural resonances. Starting from a specification procedure of the shunt characteristics, the electrical parameters are derived for shunt topologies proposed in the literature, namely Hollkamp’s shunt, the current flowing shunt, the series parallel impedance structure and the current blocking shunt. Effective vibration mitigation of multiple structural modes is demonstrated numerically and experimentally on a piezoelectric beam. Performance in terms of vibration reduction obtained with the different shunts is shown to be comparable if similar shunt characteristics are considered.

The tuning of a simplified current blocking shunt circuit able to mitigate the vibration amplitude of multiple structural resonances is addressed in this article. The proposed strategy exploits the two-port network formalism in combination with physically motivated approximations to tune sequentially the electrical elements of the different branches of the shunt circuit. The resulting tuning method does not resort to optimization algorithms and requires only the knowledge of quantities that are easy to measure experimentally. It is demonstrated both numerically and experimentally using a piezoelectric beam.
