abstract

This publication presents a novel realization of a Tuned Mass Damper (TMD) using friction bars. Because of the friction forces in the contact, they dissipate energy similar to a dry friction contact. Because of the nonlinear, amplitude depending damping behavior, it is possible to have the pure absorbing effect combined with broadband damping, which cannot be achieved by the classical, viscousely damped TMD.

Special focus is layed on the modeling aspects. The friction contact is modeled using the Harmonic Balance method, and with help of the replacement parameters the system behavior is studied.
