Title:
GRAVITY-RESTORING VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3202314
Kind Code:
B2
Abstract:
PURPOSE: To obtain a vibration control device reduced in height by setting up a table provided with actuators for controlling its inclination on a building, putting an weight rollably on it, and using a reaction in tangential force on the table, which is generated by rolling of the weight, as a damping force.
CONSTITUTION: A table 2 provided with a dropping prevention guide 7, which is inclined freely by actuators 3, is set up on a building to be vibration- controlled 6. Also a weight 1 is put rollably on the table 2, and the inclination of the table 2 is controlled to rotate the weight 1 reciprocatedly. Then a reaction on the table in tangential direction generated by rolling of the weight 1 acts as a damping force. Thus a pendulum type vibration control device reduced in height can be obtained.
