ESTABLISHING AND UPDATING THE DYNAMIC MODEL OF THE MECHANICAL SYSTEM OF HIGH SPEED ELEVATORS

A dynamic model of the mechanical system of high speed elevators is established in this paper. By considering the time-varying property of the stiffness parameters, a model updating procedure has been developed. The proposed update procedure makes use of measurement of natural frequencies and optimization technique to modify selected local physical parameters. A practical example of the model establishing and updating of an elevator has been presented. The results show that the updated model provides an excellent match with test data and is capable of accurately modelling the dynamic behavior of the elevator.
