Tuned Mass Damper
Tuned Mass Damper
A tuned mass damper is used to dampen the vibrations of a larger mass ) connected to a fixed support, usually the ground, via a spring with stiffness using a relatively much smaller mass ). The smaller tuning mass is connected in series to the larger mass via a spring with stiffness and a dashpot with viscosiity . Carefully choosing the connecting spring and dashpot gives a system that rapidly attenuates the motion of the larger mass. In this demonstration, try to choose combinations of masses (ratios of /), combinations of spring stiffnesses (ratios of /), and dashpot viscosity ratio ) to get the best attenuation. You can run, pause, and reset the initial conditions of the system at any time.
