An elevator represents a multi-body system deployed in buildings to provide vertical transportation. Vibration phenomena taking place in elevator and hoist installations may influence the dynamic performance of their components which in turn may affect ride quality of a lift car. Lateral and longitudinal vibrations of suspension ropes and compensating cables may result in an adverse dynamic behaviour of the entire installation. There is a need to predict the dynamic behaviour of elevator systems under various operating conditions. In particular, it is necessary to predict any possible failures that would require their shutdowns. This paper presents the results of work to develop adequate mechanical models of elevator systems in a multibody simulation software environment. Using these models an analysis can be performed to investigate the influence of design parameters on their performance. Simulation tests have then been carried out and the results are graphically presented through diagrams and animations, for a range of elevator parameters. Conclusions concerning their influence on elevator performance can then be formulated.
