This paper deals with the quenching problem of vortex-induced vibrations and generation of electricity by dynamic absorber composed of generator with two slots and pendulum. The experiment was made on the quenching problem of the vortex-induced vibration of one-degree-of-freedom system using this device. The numerical analysis was also carried out using the Runge-Kutta-Gill method. As a result, the followings were made clear. (1) The optimal tuning condition of natural frequency of this device was derived. (2) The vortex-induced vibration was well quenched for the wide range of wind velocity by choosing its optimum tuning condition of frequency and suitable confficient of viscous damping which is decided by generator. (3) Using the tuned device, the amplitude of the main system is quenched to 5% in experiment and to 13% in numerical calculation. (4) Its vibration state was periodic vibration. (5) The condition of maximum generation of electricity was not equal to that of minimum vibration amplitude of the main system. (6) The experimental and the analytical results were in good qualitative agreement with each other.
