Abstract
This paper deals with the problem of vibration quenching of the system with a limited power supply using a Hula-Hoop. Following was made clear from the results of numerical analysis and experiment: (1) It is confirmed that the self-excited vibration such as the one observed in automatic balancer is not capable of generating. (2) This device is very effective in the region exceeding the resonant point of the system. (3) Both vibration quenching and energy saving are able to be established by using the bearing with small rotating resistance for Hula-Hoop. (4) The experimental and the analytical results were in good qualitative agreement with each other.
