This paper proposed a new concept of Magnetorheological (MR) fluid damper, which is a passive type MR fluid damper. The passive type MR damper has no electrical devices such as sensor, power supply and power controller, and hence, it has an advantage in reliability and cost compared with conventional MR dampers. Moreover, it can automatically adjust the damping force characteristics in response to its motion. The characteristics of the proposed damper were evaluated by using a numerical code of MR fluid flow. The numerical results show that the damping force is rather dependent on the displacement than the velocity and that the equivalent damping coefficient becomes smaller with increasing the vibration frequency.
