    Abstract: The main function of a suspension system is to isolate and absorb the impact from road
    surface to vehicle body. To provide good riding comfort, a damper with variable and wide-range
    damping is highly needed. This paper presents a complete procedure from design, optimization to
    experiment for a magnetorheological (MR) damper with multiple poles. This new designed damper is
    entirely different from those conventional single-pole MR dampers, effectively by extending the
    range of damping force. Magnetic simulation has been done in the paper to provide an optimal
    structure of the damper which significantly enhances the damping force while avoids magnetic
    saturation. The new damper was also manufactured and tested. The experimental results show that the
    provided damping force can be significantly increased with the increase of input current from low to
    high speeds. Damping force can be varied by 7.41 times. It proves that this new MR damper with high
    damping force can be controlled adaptively at wide range of operation conditions. It is suitable to be
    an adaptively variable damping source in semi-active suspension systems.
