Abstract

A new concept for obtaining large rotations from small linear displacements produced by a piezoelectric stack was proposed and analyzed. The concept uses elastic and dynamic instabilities of an axially driven buckling beam. A stack-driven, buckling beam prototype actuator consisting of a pre-compressed PZT stack and a thin steel beam was constructed. The buckling beam served as the motion amplifier for driving large inertial laods, while the PZT stack provided the actuation for the displacement input. The dynamic response of the system for three preloading levels and three stack driving amplitudes were tested. The static analysis using Euler's elastic theory for a buckling beam indicates small axial displacement inputs produce large rotational angles.
