Abstract

A tuned magnetic fluid damper (TMFD) is a semi-active dynamic absorber using a magnetic fluid as a damping mass. A characteristic of the TMFD is to change a natural frequency of a sloshing. When a magnetic field is applied to a container filled with a magnetic fluid from below, the natural sloshing frequency increases and a range of a damping frequency is spread. In this paper, pressure measurements were used to control the appropriate magnetic field.
