Abstract
The present invention relates to a passive mass damper for broadband suppression of vibrations. The mass damper preferably includes a bob supported by nonlinear springs with high secant stiffness and low tangent stiffness. The mass damper is mounted on a machine or other source of vibration. The vibration generated by the machine is transmitted to the mass damper and induces off phase vibration of the bob which suppresses the inducing vibration.
