Abstract
This paper deals with a semiactive damper with a preview action. It is the purpose of this paper to discuss semiactive damper and to verify its effectiveness in suppressing impact vibration. First, from the viewpoint of an additional force method, this paper presents the principle of the semiactive damper with adaptive controllability. Then, in order to utilize the semiactive damper system, software for controlling the damper is presented. Next, for the purpose of demonstrating the capability of the newly proposed damper, an experiment was carried out. Constraints on the damper system such as preview time, initial displacement of the damper, dropping stroke of the hammerhead, etc., were varied to investigate the robustness of the semiactive damper. It was also shown that the semiactive damper could be used as a passive dynamic damper. Finally, the effectiveness of the semiactive damper with adaptive controllability for suppressing impact vibration was verified.
