Paper Abstract

The Recurve architecture is an actuation building block which combines the energy density and strain amplification of a bender with the design flexibility available through actuator arrays. While polymeric piezoelectric materials have been used in prior work to demonstrate this technology, the focus of this work was to demonstrate the use of piezoceramic materials with the Recurve architecture. To accommodate this, three basic connections were developed to allow for assembling Recurve actuation building blocks into array elements: a serial connection in which the Recurve elements are connected so that the displacement accumulates, a parallel connection in which the force from the Recurve elements sum, and a combination connection in which four Recurve elements are connected to increase both force and displacement simultaneously. These connections were demonstrated using a 2 X 2 and 4 X 2 PZT/Steel Recurve array prototype. Quasi-static experiments including free deflection, blocking force, and force-deflection, were conducted and compared to response predicted by analytical models.
