    Abstract:
    Applications of passive damping to large space space structures using viscous fluid damping elements are discussed. A heritage space qualified isolation system is described in which a similar damping element was used. A potential manifestation of the concept which could be used as the basic building block for large space trusses is described and a design process for obtaining optimum dynamic performance is outlined. Numerical estimates of the performance achievable in a large Space Station-type truss predict dramatic reductions in settling times. Another manifestation suitable for providing local or supplemental damping is described, design optimization techniques are discussed, and a proposed satellite application is presented. In this example a significant decrease in launch vibration loading without modifying the structural dynamics appears feasible.
