Damper with Complex Fluid

Abstract

We proposed a new type of viscous fluid damper with complex fluids : MF(magnetic fluid), MR(magneto-rheological fluid), MCF(magnetic compound fluid). The damper never has the sedimentation of particles. To investigate the effect of damping, we measured displacement of dampers under the fluctuating magnetic field. By comparing among the differences of damping effects by three kinds of the fluid, MCF has the largest damping effect. As the fluctuating magnetic field, the proposed damper is effective for semi-active damper.
