Future Large Space Structures (LSS) will require some means of vibration damping in order to meet system performance goals. The necessary vibration suppression may be achieved through passive or active means or through a combined passive/active control approach. The Representative System Article (RSA), developed under the Air Force/Martin Marietta Passive and Active Control of Space Structures (PACOSS) program, was designed as a generic LSS for analytic study of passive and active control approaches. A laboratory model of the RSA, referred to as the Dynamic Test Article (DTA), is being fabricated to demonstrate the design methods and performance of passive damping treatments and mechanisms. This paper presents the analytic and experimental test results for three DTA components on which modal surveys have been conducted. The results demonstrate that passive damping can be successfully designed and predicted in LSS-type structures using the modal strain energy method and viscoelastic materials.
