In this paper the problem of vibration control of a multi-member column subjected to the specific load is investigated. The vibration control is realized with the use of the piezoceramic element in the form of a rod that is connected to the host structure by means of the pins strengthened by rotational springs. The Hamilton's principle is used during formulation of the boundary problem. The results of the numerical simulations are focused on the correction of the characteristic curves shape at a different radius of the loading head.

“…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]. The piezoelectric transducer shunted with a RL couple [17], or the electromagnetic transducer shunted with a RC couple [18] are the two-order circuit that can generate an electrical resonance.…”

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.

“…A PZT actuator is capable of providing active control for structures. For the vibration control, the external disturbance is suppressed to maintain the structure in its equilibrium position, while shape control enables the structure to deform in a desired and proper shape [ 13 ]. Schulz et al [ 14 ] studied the influence of the allocation of piezoelectric patches in composite structures for vibration control using a finite element method and a linear quadratic regulator.…”

Piezoelectric (PZT) actuators bonded on a structure can be used to generate deformation and excite vibration for the shape control and vibration suppression, respectively. This article proposes a theoretical model for predicting vibrational response of a composite laminate plate with PZT actuators. The bending moment induced by the PZT actuator was obtained and applied on the composite laminate plate. Utilizing composite mechanics and plate theory, an analytical solution of the vibrational response of a composite laminate plate excited by the PZT actuator with oscillating voltage was derived. Furthermore, the finite element analysis using ANSYS software (2019 version) was carried out to compare with the proposed model with a good agreement. A parametric study was performed to investigate the influences of PZT location and frequency on the vibration. Numerical results illustrate that mode can be selectively excited provided the PZT actuator is placed in an appropriate location. Moreover, the proposed model was employed to predict the effectiveness of vibration suppression by distributed PZT actuators. The novelty of this work is that a complicated coupling problem between the composite plate and bonded PZT actuator is resolved into two simple problems, leading to a simple analytical solution for the vibrational response of a composite plate induced by PZT actuators. The proposed model has been successfully demonstrated its applications on the vibration excitation and suppression of a composite laminate plate.
