A Study of the Dynamic Damper with a Preview Action : Experiment of the Dynamic Damper with a Preview Action

抄録

This paper deals with a realization of a dynamic damper with a preview action already proposed by the authors. It is also the purpose of this paper to verify the control effect of the dynamic damper for the suppression of a transient vibration resulting from an impact force. First, this paper shows a mechanism of a newly designed dynamic damper with a preview action. Then, based upon three kinds of preview actions proposed in the previous papers, and impact experiment is carried out, verifying the effectiveness of these preview methods. Furthermore, an influence of the maximum impact force upon the control effect for the suppression of the first wave of the transient vibration is investigated. In addition, by varying preview conditions such as a preview time and an initial displacement of a damper mass, the control effect in terms of the preview action is considered.
