A Study on the Dynamic Damper with a Preview Action : 2nd Report, Experiment of the Dynamic Damper with a Preview Action

Abstract

This paper deals with the realization of a dynamic damper with a preview action proposed in the first report. It is also the purpose of this paper to verify the control effect of the dynamic damper for the suppression of a transient vibration subject to an impact force. First, this paper shows a mechanism of a newly designed dynamic damper with the preview action. Then, based upon three kinds of preview actions proposed in the previous papers, an 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 preview time and initial displacement of the damper mass, the control effect in terms of the preview action is considered.
