Aiming at the problem of low utilization rate of damping routeway on the traditional magnetorheological (MR) damper, two optimized magnetic circuit structures of design scheme were proposed. The twodimensional (2D) finite element simulation of these two types of MR damper on the magnetic structure of magnetic field was finished by using the ANSYS software, and the analysis result shows that the magnetic circuit structural designs of two types of MR damper are feasible. The output force of two types of damper was estimated by using Bingham model, from which the force velocity curve under different working conditionsare obtained. The result shows that the maximum output damping force of two improved dampers are at least doubled than the traditional damper with the same piston size due to increasing of the effective length of the damping routeway.
