DAMPING DEVICE
Document Type and Number:
Japanese Patent JPH0633636
Kind Code:
A
Abstract:
PURPOSE: To perform calculation of a control amount for a dynamic vibration absorber by estimating the vibration mode of a structure in a shorter time.
CONSTITUTION: Sensors 15a and 15b for detecting displacement are mounted to two spots of the first floor and the roof 2a of a building 2. A CPU 25 of a control device 4 counts the vibration frequency of the building 2 by means of output signals from the sensors 15a and 15b and based on an integrated value, a vibration mode is estimated. A control amount (u) on a dynamic vibration absorber 3 is computed from displacement of the roof 2a of the building 2 determined by an output difference between the sensors 15a and 15b and a constant responding to a vibration mode.
