magnetorheological damper characterization using sixth order polynomial approached.
Magnetorheological (MR) damper uses a kind of smart material which react with
magnetic field namely magnetorheological fluid (MR Fluid). In this study,
characterization of MR damper has been carried in different current based on forcevelocity
and force-displacement graph and it was validated with experimental result. The
polynomial approached was used to get the nonlinear hysteresis behavior of MR
Damper. Every coefficient ai for current domain 0.25A until 2.0A gives the equation
itself. So every coefficient ai for current domain had been collected and became only one
equation. Then, the sixth order polynomial model compared with inverse model to
capture the difference of experimental result. Inverse model is not adequately captured
the nonlinear hysteresis although the trend of its force versus velocity is still same with
experimental result. Proposed polynomial model has best fit with experimental result
and its curve closely same with experimental result. |
