Title:
DAMPING DEVICE OF ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2005/097655
Kind Code:
A1
Abstract:
A damping device of an elevator capable of improving riding comfortableness in a car by efficiently damping vibration generated in the car. A filter means is used to lower the gains of those frequency bands other than a frequency band including the lower natural frequencies of a vibration isolating means elastically supporting the car among signals obtained from a vibration measuring means installed in the car. Thus, the riding comfortableness in the car can be improved by intensively using a movable weight and a drive means for damping the vibration caused by the low natural frequencies of the vibration isolating means.
