| Research Abstract |
This report describes the development of a new type of Magneto-Rheological(MR) fluid whose typical characteristics can be controlled by the applied magnetic field strength. This MR fluid was based on grease and the dispersed magnetic particles might be supported by three-dimensional filament in the grease, and it showed quite good dispersion stability of particles. A variable damper was constructed with this MR grease and its performance was investigated. Furthermore, the variable damper was installed into a small-size structural model and the vibration mode can be varied by changing the damping property of the variable damper.
