Magnetorheological (MR) fluid dampers (16) are optimized. Dimensional relation- 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 piston 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 flow slots (56) are utilized to increase contact between the fluid and the magnetic coil (40).
