NASA Langley’s Compact Vibration Damper Technology


NASA’s Langley Research Center (LaRC) has developed a compact tuned damper to reduce vibration occurring at a fixed frequency. Tuned dampers reduce the vibration of base structures by dissipating energy. The magnitude of the dissipated energy is proportional to the square of the displacement or velocity of the tuned mass, which in turn is proportional to the range of motion. The NASA damper design allows the slider mass to achieve 2x-3x greater range of motion than that found in conventional devices. This enables 4x-9x more effectiveness for the same size and weight, or the same effectiveness for a 4x-9x decrease in weight.

LaRC, the oldest of NASA's field centers, is located in Hampton, Virginia.  The Center has focused primarily on aeronautical research; however, the Apollo lunar lander was flight-tested at the facility. Several of the earliest high-profile space missions were planned and designed onsite.

Established in 1917 by the National Advisory Committee for Aeronautics, LaRC devotes two-thirds of its programs to aeronautics and the rest to space.
