Analysis of Beams with Piezoelectric Actuators
Applied Mathematics and Mechanics, 2001Based on the two-dimensional constitutive relationships of the piezoelectric material, an analytical solution for an intelligent beam excited by a pair of piezoelectric actuators is derived. With the solution the force and moment generated by two piezoelectric actuators and a pair of piezoelectric actuator/sensor are obtained.

On the Nonlinear Behavior of Piezoelectric Actuators
Journal of Vibration and Control, 2004In this paper we present a theoretical and experimental study of the nonlinear behavior of piezoelectric actuators. The nonlinearities are introduced as quadratic terms in the piezoelectric constitutive relations. These relations are employed, together with supporting experimental results, to establish an engineering description of the nonlinearities ...

Piezoelectric modelling for an impact actuator
Mechatronics, 2003Amplification techniques for piezoelectric actuation are briefly reviewed and an unlatching impact piezo-actuator then proposed. In such a device, a piezoelectric multilayer has the function of imparting kinetic energy to a mass connected to an unlatching mechanism.

Review of Scientific Instruments, 2016
For the piezo-driven microgripper, one issue is to enlarge the grasping stroke and realize parallel grasping movement in the compact design. Piezoelectric stack actuator (PSA) and piezoelectric cantilever actuator (PCA) are two kinds of typical piezoelectric actuators. In this study, a novel microgripper hybrid driven by a PSA and two PCAs is proposed,

Actuation of a discontinuous structure with piezoelectric actuators
Journal of Sound and Vibration, 2008Abstract An alternate approach to exciting a one-dimensional structure with discontinuities using a piezoelectric actuator is presented and examined. Instead of being bonded to the uniform side of a beam, the piezoelectric actuator is attached such that it spans two adjacent rib discontinuities.
