BSc/project thesis: Development of a tool to measure surface properties on curved shapes

Beitrag von SKF-Institut » Fr, 14. Dez. 18, 15:43

Development of a tool to measure surface properties on curved shapes
(Entwicklung eines Werkzeugs um Oberflächeneigenschaften auf gekrümmten
Körpern zu messen)

Thesis:
Bachelor/project-thesis

Background:
The surface properties of marine structures play in some disciplines a very important role. In fatigue analysis the depth and shape of notches or grooves plays an important role (Figure). The surface roughness and surface profile can be well measured on straight specimens. However, if specimens are curved (Figure) the measurements are either not reliable or not functioning at all.

Tasks:
  1. Literature review on the definition and measurement of surface roughness and the state of the art of its measurement.
  2. Design a device that allows surface roughness testing on straight and moderately curved specimen.
  3. Testing of method and device on test pieces from the M-10 laboratory
  4. Applying the method on a series of flame cut specimen (see Figure 1) and
    create a database of the measured data
For the experimental and practical work the strength laboratory is providing required
support.
