The passive type MR damper has unique and useful damping characteristics with some magnetic and mechanical components in spite of its passiveness. Some excitation tests show that the damping force changes in response to the combination of the signs of displacement and velocity and it provides an excellent damping performance. In order to design the damper, the evaluation of the damping characteristics based on the analysis of the magnetic field distribution and the MR fluid flow is required. This paper introduces the evaluation method by using magnetic field analysis and algebraic equation for fluid flow. The proposed evaluation method is applied to some experimental data. As a result, the evaluated damping characteristics agree with the experimental results.
