| Research Abstract |
This study proposes a new semi-active vibration control method based on harmonically varying damping. In the case that the excitation has the natural frequency component of the system resonance is induced. However, if the modulated harmonic vibration induced by the variable damping and harmless secondary excitation is at the same frequency of the harmful excitation yet antiphase, the resonance can be reduced by interference. An expression for the variable damping controller has been developed in the case of an ideal variable damping device and control performance has been confirmed.
