Paper Abstract

Precision inflatable space structures promise revolutionary change in spacecraft design over the next decade. Given the variety of previous applications and the potential of future concepts, development of advanced design tools is underway. Validation of these models requires experimental analysis of both ground and orbiting test articles. The present study examined the suitability of piezoelectric polymer materials (namely PVDF) to excite an inflated structure for modal testing. Experiments were undertaken using both a conventional electrodynamic shaker and a small sheet of PVDF bonded to an inflated torus. In addition, a linear finite element model of an inflated torus is compared to the experimental results. The results demonstrate the potential for PVDF to excite inflatable ground test articles.
