【Abstract】 A new type of electrorheological (ER) damper which can enlarge much more damping force is designed according to the mechanic characteristics of ER fluids and the original ER damper. The model of mechanics is presented. The damping force and the equivalent viscous damping coefficient of ER dampers are investigated. The viscous damping coefficient of the new damper is 4 times of that of the original damper when the electric field is 0 kV/mm and the gain value is 2. The result shows that the new type of ER damper is theoretically feasible.更多还原
