ROTATIONAL SPEED-ADAPTIVE TUNED MASS ABSORBER AND TORSIONAL VIBRATION DAMPER WITH THE SAME

摘要

The invention relates to a rotational speed-adaptive tuned mass absorber and a torsional vibration damper with the same, having a disc part rotating about an axis of rotation and a plurality of oscillating tuned masses arranged on said disc part around the circumference along a first oscillation angle enforced along an epicycloid first pendulum track tuned to a predefined first pendulum order. To implement stops to the tuned masses at large oscillation angles with adequate oscillation isolation at large oscillation angles, the tuned masses are guided at second oscillation angles exceeding the first oscillation angles onto a second pendulum track forcing a second pendulum order modified over the first pendulum order.
