Considerations for the Application of Magnetorheological Dampers to a Crossover SUV 2008-01-0347

Magnetorheological (MR) dampers have been used in the market on various vehicles since 2001. They use a special oil-based fluid (Magnetorheological Fluid, MRF) that contains small iron particles (1-10 μm in size) and a controllable electromagnetic piston to allow a wide range of damping forces. The system's wide range of available damping force combined with nearly instantaneous response time helps maximize body control while simultaneously providing outstanding ride comfort.

This paper describes how the MR technology was combined with conventional suspension tuning to achieve an enhanced level of dynamic performance. While the MR damper offers enhanced performance, its unique response characteristics require tuning of other hardware components that could be considered to be beyond the normal tuning range for that of a conventional suspension.
