Abstract: A dual-out rod MR damper is designed and manufactured. The theoretical formulas and simulation results of the magnetic circuit by finite element method are given,and the result of magnetic field test of the gap is also presented. The relationships between damping force and input excitation and current are obtained through full scale tests. Accurate dynamic model of the MRFD is established. Finally,this damper is installed in the isolation system for shaking table test based on dSPACE system. It shows that the results obtained by the theoretical simplified calculation,finite element analysis and test are coincident. This verifies the feasibility and accuracy of the simplified calculation and finite element analysis in the preliminary design of the product. The proposed dynamic model of the damper is accurate. The controllability of the damper and effectiveness of control algorithms are verified. These works provide specific methods and ideas for future research and development of the MRFD.
