Abstract


  • In this paper, self-sensing technology was introduced into an adaptive tuned vibration absorber,

    incorporating a laminated magnetorheological elastomer (MRE) structure, a hybrid magnetic

    system and a self-sensing component. The adoption of the laminated MRE structure and the

    hybrid magnetic system enables the absorber to have higher lateral flexibility and a wider

    effective frequency range. The integration of the self-sensing capability allows the absorber to

    operate without sensors and, at the same time, greatly reduces costs, required space and

    maintenance. A series of experiments were conducted to measure the frequency shift property, to

    verify the self-sensing capability and to evaluate its effectiveness on vibration reduction. The

    experimental results show that the natural frequency of the proposed absorber can be changed to

    4.8 Hz at –3 A and 11.3 Hz at 3 A from 8.5 Hz at 0 A, the frequency of the self-sensed voltage

    equals the excitation frequency and, more importantly, the vibration control effectiveness of the

    self-sensing MRE absorber is experimentally verified and it is more effective on vibration

    reduction than a passive absorber.
