Abstract
In this paper, the authors propose a vibration control device using power generator in order to develop a small damper which was suitable for structural vibration control in space. The vibration control device consists of a ball screw, piston, ball nut, gear, power generator, and rod ends. The linear motion of the piston is converted to rotary motion by the ball screw, and then the electric power is generated as dissipation energy. A very low sinusoidal input displacement was applied to the device, and the characteristics of the damping force were examined with open circuit and short circuit of the generator. The experimental results were compared with the theoretical results.
