• This paper describes the modeling of a semi-active shock absorber that uses magnetorheological (MR) fluid, which is a material that responds to an applied magnetic field and changes its apparent viscosity. We propose a dynamic system in which the friction of a falling body is taken into consideration, and a model in which the shearing resisting force depends on the velocity of flow. The validity of this model and a Bingham model is verified by comparison of the experiment with a simulation. This study clarifies that resisting forces obtained by the simulation corresponded to those obtained by the experiment, and that the current model is effective in predicting the behavior of a MR shock absorber.
