6 Magnetorheological Fluid Technology: Applications in Vehicle Systems
one of the two eld activation parts is free to translate or rotate about the
other. Application devices operated in the shear mode include clutches [19–
28], brakes [19, 29, 30], and vibration isolation mounts for small magnitude
excitation [31–34]. Figure1.7 depicts rotational type MR clutches that can be
used for torque transmission or tension control in many dynamic systems.
