Abstract [en]

The aim of this thesis was to determine the stability criteria of an inline axialpiston pump with an eccentric control system. The hydrostatic/hydrodynamic bearings of the swash plate was inspected with model building and simulation as method. The general approach has been to regard the swash plate as stiff, leading to the hydrostatic friction between the swash plate and the pump house to be considered more or less constant. Recent research treat the swash plate as bendable which could lead to the swash plate bearings’ friction being replaced from mixed friction to a full contact interaction between the swash plate and the pump house, with an increased friction as result. This increase in friction is theorized to increase the stability ofthe pump by limiting the movement of the swash plate in comparison to the fully lubricated bearing.
