Abstract
A non-stationary distributed model of the vibration of an elevator system that accommodates the following aspects has been developed: machine and drive dynamics, the longitudinal response of the rope-car-counterweight system, the coupling effects across the traction sheave and the response to excitation sources such as the torque ripple. Hamilton’s principle is applied to derive a set of partial differential equations that describes the dynamic behaviour of the mechanical part. These equations are discretized by expanding the longitudinal displacements in terms of the modal shapes to obtain a set of ordinary differential equations. The discrete model is then solved numerically in MATLAB-Simulink. Parameters of actual lift installations are used in the simulations to analyse the response of the system. Experimental tests are carried out in order to identify the system characteristics and to validate the simulation model.
