Abstract
While most computer simulations of lubricant film behaviour in oscillating contacts are still based on isoviscous approaches, this theoretical investigation demonstrates the extensive influence of temperature effects on the tribological process. Film thicknesses and friction forces are reduced significantly when temperatures are included in the model. Bulk oil temperatures, as well as flash temperatures, are themselves dependent on the initial temperature of the system. It is shown that, compared with the load and speed parameters, changes in temperature have much more dramatic results. Finally, by means of the film thickness-speed relationship the great importance of temperature effects for the interpretation of other tribological phenomena is made clear.
