Zusammenfassung

This paper presents state of the art simulation techniques to analyse and evaluate mechanical systems with fluid film coupling. The algorithms are implemented in a stable and user-friendly software, which considers the hydrodynamic pressure build-up in the lubricated gaps as well as states of mixed lubrication when surface roughness gets into contact. Under high loads, the consideration of the interaction of the local elastic surface deformations and the pressure build-up is absolutely necessary. The analysis of the calculated tribological parameters like gaps, pressures, friction power losses and mixed lubrication areas help to optimize the design of the bearings and their elastic surroundings. The capability of elastohydrodynamic simulation is shown exemplarily on the tribological contacts of one of Delphi’s high-pressure fuel pumps.
