VIBRATION CONTROL APPARATUS FOR ELEVATOR

摘要

PURPOSE: An apparatus for controlling the vibration of an elevator is provided to maximize the vibration controlling effect of the elevator since an active vibrating device and a passive vibrating device are used together. CONSTITUTION: An apparatus for controlling the vibration of an elevator comprises an acceleration sensor and a rotating sensor(20), a vibration controller(30), an actuator(40) and a lever. The acceleration sensor and the rotating sensor are installed on the lower part of the frame of an elevator car and sense the vibration due to external force. The vibration controller feeds back a vibration signal, which has been through the acceleration sensor and the rotating sensor, and calculates control force. The actuator is controlled by an actuator controlling unit(42) for receiving the control force through the vibration controller and controls the vibration. The actuator is installed on each roller guide body.
