エレベータの振動低減装置
Document Type and Number:
Japanese Patent JP4810539
Kind Code:
B2
Abstract:
In a vibration damping device for an elevator, an actuator for generating a vibration damping force acting on an elevator car is provided in parallel with a spring for urging a guide roller against a guide rail. The actuator is controlled by a controller. The controller determines the vibration damping force to be generated by the actuator based on information from a car frame acceleration sensor for detecting horizontal acceleration of a car frame and a car cage acceleration sensor for detecting horizontal acceleration of a car cage.
