Rotating body sympathetic vibration absorber

A vibration absorber for damping the determining resonance vibrations of rotating bodies through creating sympathetic vibrations to sympathetically dampen the wheel vibrations, in particular rail wheels, comprising:

• several plates forming a unit which establish a mass;
• intermediate layers of compressible damping material separating said plates from each other so that said damping material is compressed during vibration of said plates;
• means connecting said plates with the rotating body at at least one point;
• so that the plates vibrate like the tines of a tuning fork and a vibration nodal point is established at said connecting means and
• an intermediate layer of damping material between said plates over a large remaining area thereof and coupled by connecting means to the rotating body;
• the geometric dimensions of said plates and said intermediate layers and the Shore hardness of said damping material of the intermediate layers are selected such that all plates oscillate at substantially the same natural frequency of the rotating body to be damped, and the amplitudes and phases of the vibrations of the individual plates differ, in such a manner, with respect to one another, that the damping material is distorted as strongly as possible within its elastic limit.
