The suspension systems of automobiles, trucks, motorcycles and many other vehicles customarily have passive hydraulic "shock absorber" or damper assemblies connected in parallel with springs between the vehicle frame and axle components to minimize motion of the vehicle frames and to thereby enhance the riding comfort, stability and/or safety of the vehicles. To overcome the limitations of conventional shock absorbers for vehicle dynamics, passive dampers are being increasingly replaced by adjustable dampers. Electrorheological (ER) and Magnetorheological (MR) fluids experience changes in...
