Abstract
In the paper, the magnetic field distribution
and the influence of some parameters of a metal foam magnetorheological ( MR
fluid damper, including excitation current and gap width are investigated. Metal foam (MR) fluid damper owns some
advantages, such as long lifetime and low cost. In order to analyze the effect of excitation current and gap width on magnetic
induction intensity, a series of simulations of dampers in different currents and gaps is conducted in the ANSYS FEM
software. From the simulation results, the conclusion indicate s that excitati on current and gap width are two key factors for
the damper, with the increasing of excitation current, magnetic induction intensity in the gap increases, once the current is
above 1.5A, the increment of magnetic induction intensity is not obvious longer, and the magnetic induction intensity
increases with the decreasing of gap width..
