This paper is to introduce a new method which deals with simulation of transient heat dissipation and dynamic temperature rise of elevator hydraulic systems. A computer software based upon the method proposed has been developed to predict the system thermodynamic behaviours in any instant of operation under variable load conditions, which is very significant to achieve system optimal design parameters. The simulation results obtained by this method is far more realistic compared to those calculated from the conventional method, which adopts empirical formulas and is widely used in the elevator industry. The predicated results of heat dissipation and fluid temperature rise obtained using the method proposed in this paper have been found good agreement with the measured results.
