Electrorheological(ER) damper, a kind of intelligent mechanical device which can adjust the force steplessly by using the controllable characteristic of the electric field. ER damper has many advantages such as simple structure, low power consumption, fast response time and so on, so it has been successfully used in many fields. There are few reports on the study of impact load vibration with ER damper. In this paper, operating principle of ER damper was introduced, and the mechanical model between damping force and controlled electric field based on Bingham model was built. The control system model of ER damper under impact load was built and simulation analysis of fuzzy-pi control algorithm was completed by use of Simulink. The simulation results show the fuzzy-pi control algorithm has excellent control effect.
