VIBRATION ABSORBER FOR RESONANCE VIBRATIONS OF ROTATING BODIES

摘要

Abstract of the DisclosureA vibration absorber for resonance vibrations of rotating bodies,in particular rail wheels, comprises several oscillatory plates which form orcarry the mass, are separated from one another by intermediate layers ofdamping material and which are connected at at least one point rigidly withthe rotating body and are coupled to the rotating body in the remaining areaby way of an intermediate layer of damping material. The plates (1,2,11,12,15-18) and the intermediate layers (6,7,8,9,22-25) are tuned to one anotherwith respect to their geometric dimensions, and the shore hardness of thedamping material of the intermediate layers (6-9,22-25) is that all plates(1,2,11,12,15-18) oscillate with the natural frequency of the rotating body(4,10) to be damped. The amplitudes and phases of the vibrations of theindividual plates (1,2,11,12,15-18) are in such a relationship to one anotherthat the damping material is as strongly distorted as possible.
