<p>This thesis investigates the effects of swashplate vibration
and slipper surface geometry on the performance of the slipper-swashplate
interface. The lubricating interfaces within a swashplate type axial piston
machine are the most complicated part of the design process. These interfaces
are supposed to provide support to the significant loads they experience during
operation and to prevent continuous contact of the sliding surfaces. Therefore a
proper slipper-swashplate interface design ensures full film lubrication during
operation and provides sufficient load support while minimizing viscous and
volumetric losses at the same time. The effects of two factors on the
performance of the slipper-swashplate are examined during this work; swashplate
vibration and slipper surface micro-geometry. An already existing model of the
slipper-swashplate interface was used to carry out the results for this work
however some modifications were made to the model to suit the needs of this
research. Swashplate vibration is a phenomenon that has not been implemented in
the model before, therefore its effects on the performance of the interface
were analyzed. Thickness of the fluid film in the lubricating regime corresponds
with its performance and is directly affected by the micro-geometry of the
sliding interfaces. Therefore the effects of slipper surface micro-geometry is
crucial to study in order to find the optimal slipper-swashplate interface
design.</p>
