Magneto rheological damper

A magneto rheological damper or magneto rheological shock absorber is a damper filled with Magneto rheological fluid, which is controlled by an electric field, usually using an electromagnet.^[1][2][3] This allows the damping characteristics of the shock to be modified by controlling the power of the magnet. This type of shock has several applications, most notably in semi-active vehicle suspensions which may adapt to road conditions, which are monitored through sensors in the vehicle, and in prosthetic limbs.^[4]

These types of systems are available from OEMs for several vehicles, including the Acura MDX, Audi TT, Audi R8, Buick Lucerne, Cadillac DTS, Cadillac XLR, Cadillac SRX, Cadillac STS, Chevrolet Corvette, Ferrari 599GTB, and Holden HSV Commodore.^[5] Many of these systems are produced by the Delphi Corporation under the proprietary name MagneRide.^[6]

MillenWorks has also included them in several military vehicles including the MillenWorks Light Utility Vehicle, and in retrofits to the US Army Stryker and HMMWV for testing by TARDEC.^[7]
