In this paper, the advantages of multistage piston-type MR damper are analyzed.The characteristics of the electromagnetic coils are systematically investigated.The simulation model for the MR damper is established and analyzed by means of the finite element software of Maxwell.From the model analysis, it is shown that to raise the utilization rate of the magnetic circuit, the electromagnetic coils in the damper should be connected in parallel form and conducted with inverse current.In order to improve the distribution of magnetic flux and guarantee the uniform distribution of magnetic induction in the dampers' gap, the effective length in the magnetic circuit should be adjusted and trapezoidal shaped section for the piston alveolar should be adopted.
