摘要：

Hydraulic systems that operate for long periods of time eventually develop high oil temperatures that have damaging effects on machine performance. If the temperature rise is excessive, the oil viscosity drops, lubricating properties are lost and in the worst cases the whole system can be seriously damaged. A mathematical model for predicting temperature distribution in hydraulic systems has been developed with taking into account the thermodynamic processes and the effects of heat transfer by conduction, radiation and convection. In order to test this model experimentally, a complete hydraulic mixer system has been designed, instrumented and commissioned. A software package for hydraulic systems has been developed to make accurate estimation for unsteady state temperature analysis in hydraulic systems at any time during its operation. The simulation results of this package have shown that this model is more accurate than that reported elsewhere.
