sliding multi electrode ER fluid damper was designed and manufactured, experiments for its dynamic characteristics was also conducted in this work. Based on Bingham plastic theory, a mechanical model for the ER fluid damper considering its viscous damping effect and friction damping effect was proposed. The model has a clear physical meaning with concise expression, and only three parameters need to be determined by experimental data. Optimization method was used to identify these parameters of the damper and numerical results show that this model can be used to simulate the dynamic properties of this ER fluid damper with good precision.
