Abstract
A semi-active control strategy using variable dampers had been applied for vibration control of actual buildings and vibration isolation of vehicles. In these systems, natural frequencies are very low. Thus, we thought it was very interesting that the semi-active control using variable dampers was applied for structural control whose natural frequency was high like 10-20Hz. In order to confirm possibilities of semi-active control in high frequency, we performed experiments using the variable damper and the single degree of freedom structure. In this paper, experimental results and the characteristics of variable damper will be shown. Validities and problems of variable damper for semi-active control will be described bellow.
