Abstract:
In the Structural Analysis II research project, a structure-based evaluation method
for twist on seal mating surfaces, based on findings from the Structural Analysis
I project, was expanded into a holistic procedure.
The functional evaluation of seal mating surfaces is carried out using optically measured
surface topographies. All surface structures responsible for the fluid conveying effect
are recorded and evaluated in a single measurement. Surface parameters,
which describe the functional properties of seal mating surfaces, were defined
in the course of the research project.
The
effect of various surface structures on the conveying behavior of seal mating surfaces
was investigated using fluid simulations and experimental conveying value investigations. The results of this were compared with the newly defined surface parameters
. This revealed an excellent correlation.
The methods and findings developed in the research project can be applied in practice for
quality assurance and for optimization in the manufacture of seal counter faces
.
