In this paper, the analysis of dynamic characteristics and performance investigation of the ER damper are investigated. The ER damper is based on a double rod actuator and an electric field are applied to the moving electrode composed of cylinder and piston. The performance of the ER damper is length of piston electrode field and its velocities. The experimental and calculated results show that the characteristic of the ER damper varies with the magnitude of the electric field.
