Modelling and simulations of elevator dynamic behaviour

Electric drive elevators represent a special group of transport machines for vertical lifting of a load with stressed dynamic features. Special attention should be paid to the behaviour of these devices in exploitation, as early as in the projecting phase. The paper shows the process of forming adequate mechanical models for elevators grouped according to their features, and with this an analysis can be performed of the influence of certain parameters on their behaviour in operation. Based on the formed elevator models, simulations have been performed, and the obtained results are graphically shown through diagrams, with varying "dynamic" parameters (drive characteristics, velocity and acceleration, the height of lifting, rated load and the weight of the cabin, mechanical characteristics of the rope…) with the conclusions on their influence on elevator behaviour.
