Design and Research of MR Damper for Small Displacement & Big Damping Force

This paper proposed a design plan of squeeze mode MR damper for the purpose of small displacement and big damping force and emulated the magnetic circuit based on ANSYS.The simulation results prove that design is possible.Testing shows that:With the current increases in the shock absorber,the area surrounded by indicator diagram curve is gradually increasing,and the energy consumption increases,the damping effect is improved and the damping force can be regulated in a row.From the force-velocity curve we know that the damper shows as non-Newtonian fluid and has a characteristic of nonlinearity hysteresis.
