Master Thesis: Hydrodynamic-lubrication model for textured journal bearing

Webseite Institut für Maschinenelemente und Systementwicklung

The Institute of Machine Elements and System Engineering researches the fundamental structural and tribological behaviour of machine elements and represents them in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and noise behaviour of entire technical systems with a focus on drive technology. The developed models are also used to research and develop methods of Model Based Systems Engineering as a central element of future inductive product development processes.

Journal bearings are one of the most common types of hydrodynamic bearings, which are widely used in various subsystems in engines and power trains. Their primary purpose is to support a rotating shaft. Meanwhile, high potential of surface textures in improving the lubrication performance has been proved.

In order to predict the tribological performance of textured journal bearing, a numerical model with high-quality mesh is needed on the first level. Therefore, the objective of the MA work is to develop numerical model to predict the lubrication performance of textured journal bearings. This work will be carried out within the framework of OpenFOAM.
