Abstract


  • This paper reports a novel magnetorheological fluid (MRF)-based damper, which synergizes the

    attributes of variable stiffness and damping through the compact assembly of two MRF damping

    units and a spring. The magnetic field densities of the two damping units were analyzed. After

    the prototype of the new MRF damper, a hydraulically actuated MTS machine was used to test

    the damper’s performance, including stiffness variability and damping variability, amplitudedependent

    responses and frequency-dependent responses. A new mathematical model was

    developed to describe the variable stiffness and damping MRF damper. The successful

    development, experimental testing and modeling of this innovative variable stiffness and

    damping MRF damper make the true design and implementation of the concept of variable

    stiffness and damping feasible.
