Abstract
Damping properties of a damper using magnetic compound fluids are investigated experimentally. In this study, we focus on the effects of frequency of forced vibration on the damper utilizing magnetic compound fluids containing a fibrous material such as alpha-cellulose. Increase of alpha-cellulose in the magnetic compound fluid increases the maximum damping force. However, adding alpha-cellulose to the magnetic compound fluid leads to the small magnification ratio of damping force by applying magnetic field.
