Abstract
This paper deals with a method of designing a dynamic damper with the preview action proposed in the previous papers. It is the purpose of this paper to achieve an optimal design of the dynamic damper with the preview action, which is applied to a vibratory system with damping. First, in order to attain a systematic design of the dynamic damper system, a modern control theory is used, and two kinds of design equations are derived ; one for optimal design parameters and the other for optimal preview action. Then, from the viewpoint of nonlinear programming, these equations are solved, presenting design charts of the dynamic damper with the preview action. Furthermore, a dominant factor of the control effect is investigated. Finally, the design procedure proposed in the present paper is applied to a conventional dynamic damper, and the control effect for the suppression of impact vibration is discussed.
