ABSTRACT:
Several improved embodiments of surface effect dampers that produce a damping force including both hysteretic and frictional components. Various improvements include an amplitude sensitive feature or decoupler mechanism to eliminate or greatly reduce the damping for low amplitude input conditions as compared to high amplitude inputs, provisions for increasing the damping force in a non-linear manner, and features for providing significantly greater damping in one direction than the other. Other embodiments include an improved rotational surface effect damper useful for damping rotational motion, and a multiaxial damper which can be used, for example, as a motor mount which has the capability for the piston to tilt relative to the axis of its piston rod, allowing accommodation of torsional rotation of the engine while not compromising vibration isolation.
