Tuned Mass Dampers
Tuned Mass Dampers (TMDs) are passive devices used to reduce the dynamic response of structures subjected to dynamic loads, such as wind or seismic forces. In the context of space and astronautical engineering, TMDs are used to mitigate the effects of vibrations on spacecraft and launch vehicles. TMDs consist of a mass-spring-damper system that is tuned to the frequency of the structure's vibration modes. When the structure vibrates, the TMD oscillates out of phase with the structure, effectively reducing the amplitude of the vibration. TMDs are commonly used in tall buildings, bridges, and other civil engineering structures to reduce the effects of wind-induced vibrations. In space and astronautical engineering, TMDs are used to reduce the effects of vibrations on sensitive equipment, such as telescopes and scientific instruments.
