ABSTRACT:
This invention relates to suppression of vibrations in massive systems including large rotating elements such as induction fan rotors used in electric power generating plants. In particular, this invention relates to the provision of a tuned vibration absorber with very low damping, often known as a dynamic vibration absorber, which acts to reduce or suppress the vibration of a system having a resonant frequency near its operating frequency.
