A tuned mass damper (TMD), also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce the amplitude of mechanical vibrations, that consists of a mass that is mounted on one or more damped springs. The oscillation frequency of the mass is tuned to be similar to the resonant frequency of the object they are mounted to. Tuned mass dampers are used to reduce the maximum amplitude of the object while weighing very much less than it.
