Abstract


  • This paper presents the development of an innovative seat suspension working with a rotary

    magnetorheological (MR) fluid damper. Compared with a conventional linear MR damper, the

    well-designed rotary MR damper possesses several advantages such as usage reduction of

    magnetorheological fluid, low sealing requirements and lower costs. This research starts with the

    introduction of the seat suspension structure and the damper design, followed by the property test

    of the seat suspension using an MTS machine. The field-dependent property, amplitudedependent

    performance, and the frequency-dependent performance of the new seat suspension

    are measured and evaluated. This research puts emphasis on the evaluation of the vibration

    reduction capability of the rotary MR damper by using both simulation and experimental

    methods. Fuzzy logic is chosen to control the rotary MR damper in real time and two different

    input signals are considered as vibration excitations. The experimental results show that the

    rotary MR damper under fuzzy logic control is effective in reducing the vibrations.
