Paper Abstract

This paper presents some findings from work in progress to investigate the efficacy of using active materials to control mechanical vibrations. The device under study is designed to be useful for a range of precision positioning, force cancellation, and vibration isolation tasks typically associated with spacecraft environments. It incorporates shape-memory-alloy springs to provide an adaptive-passive isolator stage, and multilayer electrostrictive ceramic actuators for precise positioning and canceling transmitted forces across a support interface. Device performance in each of these three modes is explored by simulations incorporating characterized properties of the individual active material components.
