Abstract

This paper proposes an approach to integrate sensitivity-based shape optimization into the process of product design. The approach is based on B-Spline volume morphing boxes as an interface between the CAD model and the FE model used for optimization. Existing tools within a CAD system are used to emulate B-Spline morphing boxes. In order to use morphing boxes for sensitivity-based shape optimization, a Python program is implemented producing morphing box data that is passed to the optimization software. A consistent workflow is devised that starts with an initial CAD model and ends with a CAD model that has been updated based on optimization results. The workflow is validated on an industrial example.

In diesem Beitrag wird ein Ansatz eingeführt, um die ´sensitivitätsbasierte Formoptimierung in den Produktentwicklungsprozess zu integrieren. Der Ansatz basiert auf B-Spline-Volumen-Morphing-Boxen als Schnittstelle zwischen dem CAD-Modell und dem für die Optimierung verwendeten FE-Modell. Bestehende Werkzeuge in einem CAD-System werden verwendet, um B-Spline-Morphing-Boxen zu nachzubilden. Um Morphing-Boxen für die sensitivitätsbasierte Formoptimierung zu verwenden, wird ein Python-Programm implementiert. Dieses erzeugt die Morphing-Box-Daten, die an die Optimierungssoftware übergeben werden. Es wird eine konsistente Prozesskette entwickelt, der mit einem ersten CAD-Modell beginnt und mit einem CAD-Modell endet, das basierend auf Optimierungsergebnissen aktualisiert wurde. Die Prozesskette wird an einem industriellen Beispiel validiert.German
