In this paper, we suggest the new intelligent fluid applying MR fluid, and new base-isolation system using that new intelligent fluid. At first, new intelligent fluid suggested in this paper as MSF (Magnet Solidification Fluid) consist of some magnetic fluid and special particles. The most remarkable characteristic of the MSF is that this fluid gives stable and optional yield sharing stress by gathering the properties of containing materials. By the way, in the region where the earthquake often occurs, buildings and industrial equipments must be provided for earthquakes. Then, fuse property is considered as the most anticipative idea for base-isolation system at present. That is, base-isolation system holds an upper structure by stable holding force at usual condition or slight earthquake. On the other hand, when a severe earthquake occurs, it releases holding force and insulates transfer of excitation force of earthquake at the isolation layer of system by yielding relative displacement between ground and an upper structure. According to such idea, we developed new base-isolation system utilizing characteristic of MSF.

In this paper, a test model of a vibration isolation system with magnetorheological (MR) damper is introduced, and a simplified model using the time delay to describe the dynamic process of mechanical response and electromagnetic response for the MR damper is presented. Based on simulation, the performance evaluation with different control strategies, especially, the effects of time delay are investigated. The results show that the performance of the controlled system is highly dependent on the choice of the control strategies, and the effectiveness of semi-active on-off control is significantly determined by the time delay from the command current signal to the magnetic field of the MR damper.
