An apparatus (40) is connectable between relatively movable parts (12, 14) to resist relative vibration of the parts. The apparatus comprises a first ring-shaped member (50) having a first platform surface (54) engageable with one part (12). A second ring-shaped member (60) has a second platform surface (64) engageable with another part (14). One of the first and second ring-shaped members (50, 60) defines a series of sealed fluid chambers (48) located between the first and second members (50, 60) and spaced apart from each other around the first and second members. Each chamber (48) contains a fluid having a resistance to shear which varies in response to an energy field acting on the fluid. Each chamber (48) has its own respective blade member (42) connected to one of the first and second members (50, 60). The blade member (42) extends into the associated chamber (48). Each chamber (48) has its own respective pair of electromagnets (90, 92) for applying an energy field to the fluid in the chamber to vary the resistance to shear of the fluid as a function of the energy field acting thereon. The movement of the blade member (42) in the chamber (48) is resisted by the fluid.

An apparatus connectable between relatively movable parts to resist relative vibration of the parts along an axis, said apparatus comprising: a first ring-shaped member having a first platform surface engageable with one part; a second ring-shaped member having a second platform surface engageable with another part; at least one enclosure member disposed between said first and second ring-shaped members, said at least one enclosure member having a first end and a second end; a first radially extending end wall connected to one of said first and second ring-shaped members and to said first end of said at least one enclosure member; a second radially extending end wall connected to one of said first and second ring-shaped members and to said second end of said at least one enclosure member; a portion of one of said first and second ring-shaped members, said first and second radially extending end walls, and said at least one enclosure member defining a sealed fluid chamber between said first and second ring-shaped members and which is curved about the axis, said sealed fluid chamber containing a fluid having a resistance to shear which varies in response to an energy field acting on the fluid; a blade member connected to one of said first and second ring-shaped members and extending into said sealed fluid chamber, said blade member being curved about the axis; and means for applying an energy field to the fluid in said sealed fluid chamber to vary the resistance to shear of the fluid as a function of the energy field acting thereon, the movement of said blade member in said sealed fluid chamber being resisted by the fluid to resist relative vibration of said first and second ring-shaped members and thereby to resist vibration of the parts.
