Abstract
We have developed a simulator for evaluating the cage vertical vibration of an elevator. It enables an engineer to evaluate the cage vibration in the design stage of an elevator. The simulator is composed of an elevator mechanical model and a controller model. It can evaluate the cage vibration as the cage moves in the hoistway. It thus allows the cage vibration of a design to be checked before production, and the elevator structure can be re-designed to reduce the cage vibration if the estimated cage vibration is too large. As a result, the need for actual elevator vibration testing can be reduced.
