Development and experimental characterization of a large-capacity magnetorheological damper with annular-radial gap

Abstract Magnetorheological (MR) dampers with bypass arrangements and combined annular-radial fluid flow channels have shown superior performance compared to conventional MR single annular/radial gaps. Achieving a higher controllable dynamic force range low off-state but high on-state damping is yet significant challenge for developing payload ground vehicle suspensions. This paper presents the conceptual design, fabrication, experimental characterization of mid-sized large-capacity damper equipped compact valve. Extensive tests were conducted investigate characteristics proposed considering wide ranges excitation frequency, loading amplitude, electrical current. The equivalent viscous calculated as functions conditions considered. initially realized maximum 2.3 5.54 kN, respectively. With valve design modifications, substantially increased, reaching 5.06 6.61 effectiveness was subsequently identified by comparing its other in previous studies. results confirmed potential application highly adaptive suspension systems off-road wheeled tracked vehicles.
