摘要:
A passenger car of an elevator is transversely vibrated when it is hoisted up or down due to curves in guide rails and level differences at joints of the guide rails. An elevator vibration control apparatus of this invention employs a vibration or displacement sensor attached to a passenger car chamber to detect such transverse vibration of the passenger car. A controller calculates an operation quantity of an actuator to cancel the detected vibration of the passenger car. According to the calculated operation quantity, a servomotor is driven to displace the passenger car in a direction to cancel the transverse vibration and suppress force applied to the passenger car. As a result, the transverse vibration of the passenger car is reduced, and comfortableness of riding in the passenger car is improved.
