Gestaltbasiertes rechnergestütztes Toleranzmanagement: Entwicklung eines neuen methodischen und rechnergestützten Frameworks für die Montage- und Bewegungssimulation basierend auf Skin Model Shapes (ShapeCAN)
Zusammenfassung der Projektergebnisse
Tolerance analysis offers a quantitative design tool for assessing the effects of inevitable geometrical part deviations on the function and quality of mechanical assemblies. Consequently, it enjoys wide acceptance in industry and is a prominent research issue. However, established tolerance analysis approaches and available commercial software packages imply severe shortcomings, particularly regarding the consideration of form deviations. Motivated by this, the concept of Skin Model Shapes has been developed as a novel paradigm for the geometrical variations modelling. In this context, the research project aimed at elaborating methods and tools for the generation, assembly, and kinematic analysis of rigid Skin Model Shapes for the use in computer-aided tolerancing. The main project results are approaches for the simulation and generation of Skin Model Shapes during early as well as later design stages, models for the contact and assembly simulation between rigid Skin Model Shapes, models for the simulation of the kinematic behavior of Skin Model Shape assemblies for motion tolerancing, and a computational platform as well as a methodological framework for the computer aided tolerance analysis based on Skin Model Shapes. Hence, the project was an important step towards a coherent and complete computer-aided tolerancing process.
