A class of electrorheological (ER) dampers was analyzed using a linear approximation to the non-Newtonian ER Poiseuille flow equation. These dampers feature multiple concentric cylindrical ducts which can be interconnected in parallel, in series or in combination. The hydraulic connectivity of the ducts determines, to a great extent, the force-velocity relationship of the device. Within the overall size constraints, a tradeoff between the field-controllable force range and force magnitude is controlled by the format of the ducts. Other design variables such as the across-flow dimension of the ducts and the number of ducts were considered.
