Abstract

MULTIPHYSICS NUMERICAL ANALYSIS OF MR DAMPER WITH EXPERIMENTAL VALIDATION

Abstract

Multiphysics numerical analysis , which are the
magnetic field and time-dependent CFD analysis, validated by experimental
results have been performed to obtain the magnetic flux density and
relationship of damping force-displacement. The most effective levels of the
design parameters  have been determined
regarding of the damping force and dynamic range. Also, the expected
performances of the optimal MR damper designs and effect each design parameter
on performance have been calculated statistically corresponding to different
velocity values. Results showed that, from 0.05 m/s to 0.15 m/s of piston
velocity, the effect of the gap width was increased by 2.56% while the active
length was decreased by 4.12% under constant current.
