Magnetorheological (MR) fluid dampers (16) are optimized. Dimensional relati on- ships involved in the flow of magnetic flux are related to an operational parametric ratio of magnetic flux density in the fluid to the flux density in the steel. A magnetic valve (30) is utilized to change the flow parameters of the MR fluid and, hence, the operational char- acteristics of the damper (16). Several embodiments depicting improved pisto n designs, including spool as well as toroidal configurations, are disclosed. In addition, both single (16) and twin-tube (16) housing designs are presented, along with several sealless designs. Baffle plates (50) and toroidal magnetic segments (40) interspersed with flo w slots (56) are utilized to increase contact between the fluid and the magnetic coil (40).</ SDOAB>
