Abstract: A magnetorheological fluid (MR fluid) shock absorber model is analyzed theoretically using Newtonain fluid and idealized nonlinear Bingham plastic model respectively for the mixed mode of flow mode and shear made. In the light of the technician requirements for Chang an mini-automobile, a MR fluid shock absorber is designed and fabricated using commercial MR fluid. The nonlinear MR fluid shock absorber model is validated experimentally. The results reveal that the shock absorber model is reasonable and the MR fluid shock absorber for a specific application can be designed according to the MR fluid shock absorber model presented.
