Magnetorheological Dampers (MR dampers) have been growing in popularity in research and industry. Their ability to electronically tune and control damping behavior independently of piston velocity has enabled engineers to design desired damper responses both quickly and efficiently. This is possible due to the use of MR fluids in lieu of hydraulic fluid with the addition of an integrated electromagnet in the piston. MR dampers are notoriously complex to mathematical model due to their many sources of both known and unknown sources of non-linearity. The experimental approach will be investigated in this study. Where nonlinear aspects of MR dampening will be investigated, and curve fitting approaches explored.
