“…Rapid developments in intelligent biomedical devices using piezoelectric laminated slightly curved beams (PLSCB) actuators have been proposed, which include a piezoelectric cell stretching device (Clark et al, 2000), a stimulator for cultured bone cells (Tanaka, 1999), a device for straining flexible cell culture membranes (Schaffer et al, 1994) and a novel piezoelectric forceps actuator for minimum invasive surgery (Susanto and Yang, 2004;Susanto and Yang, 2007;Susanto, 2008). Furthermore, the piezoelectric actuators also have been used in controlling the shape of the satellite antenna (Washington, 1996;Granger et al, 2000) and damping of wings (Crawley and de Luis, 1987).…”

a b s t r a c tPiezoelectric laminated slightly curved beams (PLSCB) is currently one of the most popular actuators used in smart structure applications due to the fact that these actuators are small, lightweight, quick response and relatively high force output. This paper presents an analytical model of PLSCB, which includes the computation of natural frequencies, mode shapes and transfer function formulation using the distributed transfer function method (DTFM). By setting the radius of curvature of the proposed model to infinity, a piezoelectric laminated straight beams (PLSB) model can be obtained. The DTFM is applied and extended to carry out the transfer function formulation of the PLSCB and PLSB models. This method will be used to solve for the natural frequencies, mode shapes and transfer functions of the PLSCB and PLSB models in exact and closed form solution without using truncated series of particular comparison or admissible functions. The natural frequencies of the cantilevered PLSCB and PLSB are calculated by the DTFM and the Rayleigh-Ritz method. The analysis indicates that the stretching-bending coupling due to curvature has a considerable effect on the frequency parameters. Increasing the radius of curvature of the PLSCB has its largest effect on the natural frequencies. But the inhomogeneity of the boundary conditions does not have any effects on the natural frequencies or system spectrum due to the both receptance and boundary transfer functions have the same characteristic equations. The method can also be generalized to the vibration analysis of non-piezoelectric composite beams with arbitrary boundary conditions.

“…The distributed transfer function method (DTFM) was first applied to analyze a self-sensing beam with a piezoelectric actuator (Yellin and Shen, 1996) and then was used to model piezoelectric curved beam actuators (Susanto, 2008, 2009). Tan and Lai (2009) applied DTFM to formulate and analyze the response of piezoelectric energy harvesters.…”

The purpose of this paper is to investigate the effect of boundary flexibility on the performance of piezoelectric vibration energy harvester (PVEH) beam systems, which has not been studied comprehensively in the literature despite its importance. The coupled electromechanical equations of motion of a piezoelectric cantilever beam with a tip mass are established, with the base boundary constrained by translational and rotational springs. An exact closed-form solution of the frequency response function (FRF) of the PVEH is obtained by the distributed transfer function method (DTFM). The DTFM is a systematic powerful tool for the dynamic analysis of distributed parameter continua with non-classical boundary conditions, intermediate constraints, coupled fields, and non-proportional damping without adding much complexity to the solution formulation. Moreover, the DTFM computes the derivatives of the response, that is, the strains, which are required in the electromechanical coupling formulation, simultaneously without any differentiation. Numerical results showing the effects of boundary flexibility on energy harvesting efficiency are presented. A first-order rational function relating the boundary stiffness parameters and the harvesting efficiency is determined by nonlinear curve fitting of the calculated data. Physical insights and applicability of this analytical function for end-of-line quality check of the boundary of PVEH are discussed.

Piezoelectric laminated curved beams or laminated curved smart beams, one of the most popular elements, are widely used in nano- or micro-electromechanical systems due to their excellent properties such as small volume, lightweight, and quick response. In this article, the finite deformation of piezoelectric laminated curved beams is analyzed based on Lagrangian and Eulerian description. The piezoelectric actuating character for the deflection in the curved beams bonded with piezoelectric film (polyvinylidene fluoride) driving layers is investigated. Choosing the deformed radius of curvature and tangent slope angle as fundamental parameters, the governing equations of laminated curved smart beams under static mechanical and electrical loadings are derived. First, the equilibrium equations are deduced and decoupled using the deformed angle of tangent slope as the only variant. And then the analytical solutions of laminated curved smart beams are presented using harmonic functions. Finally, the static deformations of the laminated curved smart beams are calculated by this method and the finite element method. The results exhibit good consistency and show the validation of the present method. Circular and spiral beams covered with piezoelectric layers are researched further. Effects of radius, thickness ratios, and stacking sequence on deflections of the piezoelectric laminated beams are explored as well.
