This study is to explore the controllable ratio of damping characteristics based on a serial multielectrode electrorheological(SMER) flow mode damper. The SMER damper is applied to the two-degree-of-freedom model of a suspension system. Semi-active suspension control system equipped with the SMER damper and the fuzzy controller is designed for the evaluation of the performance of the SMER damper. The SMER damper is designed, fabricated and tested. The design method for ER dampers based on the requirements of the system damper such as controllable damping force, controllable ratio and the ratio of rebound damping force and compression damping force is described. The experimental results of the semi-active control system have demonstrated that the displacement and the acceleration power spectral density are significantly reduced by applying the semi-active control on the SMER dampers. The simulation and experimental time and frequency response of the displacement and the acceleration indicate the effectiveness of the design of the SMER damper.
