摘要

A variety of robust, high-strength, magneto-rheological (MR) fluids and devices that enable the benefit of controllable fluid technology are now commercially available. MR fluid dampers that provide semi-active control in an automotive primary suspension, seismic and wind damage mitigation in civil engineering structures or real-time gait control in an artificial leg have been introduced. Rotary MR brakes that provide semi-active control in applications ranging from NASA spacecraft to vehicular steer-by-wire systems are now in use. The key to success in all of these implementations is the ability of MR fluid to rapidly change its rheological properties upon exposure to an applied magnetic field. Details of these applications are discussed.
