Motivation:
Classical geometric tolerance analysis usually assumes rigid part behavior and neglects both manufacturing-related deviations and deformation effects during operation, although both can significantly affect functional performance. To enable a more realistic and functional tolerance analysis therefore requires these effects to be considered consistently and efficiently at an early design stage.
This thesis addresses this challenge by contributing to the coupling of structural and local contact deformation models within a unified Skin Model Shapes-based tolerance analysis framework. Skin Model Shapes are digital representations of real, imperfect part geometries that include surface variations from their nominal shape. Based on this, the thesis supports a more realistic analysis of how deviations and deformations affect the functional behavior of mechanical assemblies.
✓ The core computational framework has already been developed as the foundation for this thesis.
