WebA pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a … WebTuned mass damper (TMD) is a vibrating mass that moves out of phase with the perturbing force inducing vibration in the structure the TMD is installed on. With its out of phase motion, the inertial force of the TMD mass abates the resonant vibration of the structure by dissipating its energy.
