Summary
In recent years, numerical simulation has become one of the most significant parts of the product development cycle. To speed up the design and simulation processes, it is critical to update the CAD model before starting the simulation. Using a unique methodology, this paper offers a way for modifying and reducing a design geometric model for finite element simulation. It entails the idealisation of CAD geometry by removing minor details or reducing it to lower order representations. This is necessary because features, such as holes or fillets, are stress hubs, requiring a refined mesh, which increases processing time without providing more precision in a large scale. On the other hand, when we need to go into depth and fatigue analysis, this precision is necessary; as a result, a regulated sub-section of the entire finite element model will be applied, ensuring a robust analysis, and allowing the entire product to be easily updated. The approach developed here focuses on the integration of adaptation and idealization processes of FEA models to deal with the dynamic behaviour of an automation process, this will be accomplished by working in PTC Creo as CAD-modelling environment on the one hand, and Ansys Workbench on the other hand. An application on an existing project of this adaption process is presented in the Case Study section.
