摘要

This paper presents vibration testing and finite element analysis of an inflated thin-film torus. Inflatable structures show significant promises for future space applications. However, their extremely lightweight, flexible, and high damping properties pose difficult problems in vibration testing and analysis. In this paper, we experimentally show that smart materials could be used as sensors and actuators for performing vibration tests of an inflated torus. In addition, we developed a predictive model that can be compared with experimental results. A commercial finite element package, ANSYS, is used to model the pre-stressed inflatable structure. Both experimental and finite element results are in good agreement with each other. The predictive model can be used for analyzing the dynamics of inflated structures, and for designing control systems to attenuate vibration in an inflated torus.
