Abstract

Compared to the double-ended magnetorheological (MR) dampers, single-ended MR dampers are more suitable in limited-space required fields for their larger strokes. An accumulator is needed for a single-ended MR damper to balance the volume changes as the piston pulled out and back into the cylinder. Since an accumulator has a great influence on the damper's performances, this influence should be taken into account in the damper's designing procedure. In this paper, damping force formula is deduced for the single-ended MR damper with spring accumulator. Then both the method of determination main parameters of regular spring accumulator and its inherent drawbacks are presented. Finally, by utilizing the pseudoelastic character of shape memory alloy (SMA), a SMA spring accumulator is proposed and its design method is given as well.
