Paper Abstract

This paper presents results of ongoing research on a multifunctional actuation system wherein the strength-giving members of a small, planar, lightweight space structure also enable actuation for purposes such as shape control and steering. The configuration currently being studied includes a circular membrane with a circumferential waveguide/conductor, which also serves as a stiffener. The waveguide is end-excited by a ceramic piezoelectric microactuator. The goal of this research is to investigate the dynamic response characteristics of this system. In this paper, a theoretical model for the overall dynamics is outlined, and a few general results are presented. Experimental results aimed at studying the transient response and steady-state response characteristics of the system (and obtained using an optical profiler with dynamic measurement capability) are also included. Potential configuration changes to improve the transient and steady-state response are discussed.
