Energy-Recycling Semi-Active Method for Vibration Suppression with Piezoelectric Transducers

A semi-active vibration control technique using piezoelectric actuators with switched inductance shunts has been studied. This technique can be used for not only vibration suppression but also energy harvesting. In order to design semi-active vibration control systems and energy harvesters using this technique efficiently, it is necessary to analyze and understand the effects of design parameters on the performance of these systems. Responses of these systems to harmonic disturbance forces can be used for performance evaluation and previous studies analyze periodic responses of semi-active vibration control systems by assuming sinusoidal displacement responses and using method of harmonic balance. However, this control technique induces rectangular control forces and the displacement responses are distorted. Enhancing the control forces leads to stronger distortion of the responses and the validity of the assumption of the previous studies becomes lost. In order to overcome this problem, the authors have proposed to use shooting method which is a numerical method to calculate periodic solutions of non-linear systems without assuming certain forms of responses. This paper presents periodic responses obtained by shooting method with an improved non-dimensional model and the periodic responses are compared with ones obtained by method of harmonic balance. Furthermore, this paper considers not only the periodic responses but also non-periodic chaotic responses obtained by long term simulations with the non-dimensional model.

“…The first aim of this work is, therefore, to confirm the effectiveness of the energy-recycling semi-active method on beam structures that are typical continuous structures and are used in many engineering applications. To do this, we first present the energy-recycling method 12) to suppress multiple-mode vibration of a beam structure with multiple transducers and derive several control logics based on active control theories. Second, we simulate suppression of multiple-mode vibration of the beam structure by using the energy-recycling method in order to compare its performance with that of a conventional semi-active method and optimally tuned passive methods.…”

An innovative method of semi-active vibration suppression based on an energy-recycling approach using piezoelectric transducers is described. Piezoelectric transducers attached to or embedded in structures can convert the mechanical energy of the structure into electrical energy or, conversely, electrical energy into mechanical energy. Conventional methods have focused on how to effectively dissipate the transferred electrical energy. With our new energy-recycling method, the electrical energy is stored in the transducer functioning as a capacitor and is reused to suppress vibration of the structure, instead of simply being dissipated. This paper presents an advanced energy-recycling method to suppress multiple-mode vibration of beam structures with multiple transducers. Several control strategies based on active control theories are derived from formulae on the dynamics of a beam structure with piezoelectric transducers and electricity. We demonstrate the ability to suppress not only transient vibrations but also vibrations excited by sinusoidal and random forces.

“…In the last years, Clark proposed a state-switched method (Clark, 1999) in which piezo-elements were periodically held in an open-circuit state, then switched and held in the short-circuit state synchronously with the structure motion. Another type of semi-active control, which has been receiving much attention in the recent years, is called the pulse switching technique (Richard et al, 1998;Onoda et al, 2003;Makihara et al, 2005). It consists in fast inversion of voltage on the piezo-element using a few basic electronic elements synchronized with the mechanical vibration.…”

The present work focuses on the study and analysis of vibrations generated by the electrical motor of a wiper system on its support bracket referring to an hatchback vehicle passenger car. In the electric motor of the wiper system there can be present an imbalance transmitting vibrations to the main body via the support bracket. In this paper, after a short resume of available synchronized switch shunt damping methods, a preliminary experimental evaluation of their potential performance on noise control of the wiper system is reported. After preliminary experimental measurements of dynamic vibration by the use of vibrometer laser both on the real hatchback car then in laboratory environment, a numerical model has been created to evaluate deformations of the support bracket for comparison with the experimental data. This work realizes the preliminary numerical/experimental characterization activity to set up a new application of a control system based on a semi-active technique, called Synchronized Switch Shunt Resonator (SSSR).
