Abstract: A magnetorheological damper device is provided having a high-bandwidth and high-control ratio, which enhances the performance of the damper. The damper generally includes a cylindrically shaped housing; a magnetorheological fluid disposed in the cylindrically shaped housing; a piston assembly disposed within the cylindrically shaped housing in sliding engagement with the cylindrically shaped housing defining a first chamber. The first chamber is in communication with a second chamber, through a magnetorheological valve assembly which comprises of a plurality of cylindrically shaped fluid passageways extending from the first chamber to the second chamber, and an electromagnet; and a power supply in electrical communication with the electromagnet.
