A torsional vibration damper of the type having a hub which carries an outer inertia ring coupled thereto by an elastomer. Supplemental damping is added to the system via the use of dry friction. A broad frequency range of effectiveness is provided by designed non-linearity of the device made possible by the dry friction. A greater broadening of the frequency range of effectiveness is made possible by utilizing a plurality of inertia masses carried by the hub, all mounted on the same elastomer. Elastomeric compression is utilized to spring-load the friction surfaces, providing a series-parallel, elastomer viscous-dry friction damping medium. In multiple mass application the concept of mass interaction is utilized to further determine the dynamic performance of the damper.
