Abstract: Damping properties of a damper utilizing magnetic particles are
investigated experimentally. A group of magnetic particles is treated as the
working fluid in a damper instead of oil. In the presence of magnetic field,
the damping force of the particles damper drastically increases. The maximum
damping force appears near the dead center of vibration and higher frequency
produces stronger maximum damping force, when the vibration frequency is in the
range of low frequency below 5 Hz.
