Abstract
A tapered magnetorheological (MR) valve includes a first fixed housing that remains in a fixed position along a central axis of the tapered MR valve. The first fixed housing defines a first surface of a MR fluid channel that is at an angle with respect to the central axis of the tapered MR valve. A second housing moves linearly along the central axis of the tapered MR valve. The second housing defines a second surface of the MR fluid channel that is at the angle with respect to the central axis of the tapered MR valve. The first fixed housing and the second housing together define a first MR fluid chamber and a second MR fluid chamber interconnected by the MR fluid channel. The second housing moves linearly between a first position and a second position along the central axis of the tapered MR valve. The distance between the first surface of the MR fluid channel and the second surface of the MR fluid channel has a first value at the first position and a second value greater that the first value at the second position.
