Apparatus, and a related method, for damping vibrations in a flexible structure by a combination of tuned mass damping and particle damping. Combining the two damping techniques in a single apparatus provides a desirable frequency response characteristic that provides damping over a wide frequency range and, because the apparatus is relatively insensitive to temperature changes, provides reliable damping in space structures exposed to extremes of temperature. Damping with the apparatus can be tuned and adjusted by selection of appropriate components for the tuned mass damping portion and, in the particle damper portion, by selection of a tuning beam length, the size and material of particles, and a particle container gap height.
