By dynamic analysis, the dynamic modeling of designed magnetorheological(MR) shock absorber with metering pin is established, and using the experimental data. The relation of kinematic viscosity and current, and shear stress and current are respectively identified, and the parameters of dynamic model are identified by the least square identification method. The experiment results show that the identified model has high accuracy, and can be used for the performance analysis and control system design of the shock absorber.
