This paper deals with the vibration control device that simultaneously generates electricity by using absorbed vibration energy. This device is composed of a generator and a Hula-Hoop that is fixed on the shaft of the generator. As the conditions which have some effect on the vibration control performance and electric power, power of D.C. motor that is the substitute of generator, weight of Hula-Hoop, distance between the center of rotation and center of gravity, external frequency, and initial condition are examined. As a result, the followings were made clear. (1)Hula-Hoop rotates synchronously with the vibration of main system. (2)The resonance amplitude of main system is quenched up to about 1/3 and D.C. motor generates electricity as generator. (3)Appropriate weight of Hula-Hoop and initial condition are necessary to rotate Hula-Hoop, control vibration and generate electricity. (4)Generating electric power is proportional to the second power of external frequency. The experimental and the anlytical results were in good qualitative agreement with each other.
