508 Semi-active vibration control for transverse vibration of elevator-rope

Abstract

This paper presents the vibration control, using passive or semi-active dampers, for the transverse vibration of an elevator rope. The dampers are located in the vicinity of the top end of rope and the vibration of rope is reduced by impact with the dampers. The adequate gap width, location, and damping coefficient of the damping device are calculated for the case in which the arbitrary constant length of the rope is allocated and the building is subjected to various earthquakes. Further, the performance of the semi-active vibration control method for the suppression of the vibration of rope is verified; consequently, the usefulness for the proposed method is shown.
