Job Responsibilities:
Hintergrund
Bei gedruckten elektronischen Schaltungen werden die elektronischen Bauteile auf die Leiterplatte aufgelötet, wobei die Leiterplatten eine komplexe Struktur aus Kupferschichten und faserverstärktem Epoxid darstellt. Die Kupferschichten bilden dabei die Leiterbahnen zwischen den elektrischen Bauteilen ab und das faserverstärkte Epoxid dient als Trägermaterial. Da alle diese Strukturen sehr kleine geometrische Abmessungen zur Gesamtgröße der Leiterplatte besitzen, müsste man ein extrem feines Netz verwenden, um die Strukturen auflösen zu können. Dies resultiert in Simulationsmodellen mit sehr vielen Freiheitsgraden und großen Rechenzeiten. Für dynamische Untersuchungen der Leiterplatte ist eine Näherung durch eine grobe Elementierung ausreichend, wobei jedoch jedem Element ein orthotropes Material zugewiesen wird, das die Eigenschaften der im Element eingeschlossenen Feinstrukturen möglichst gut annähert. Dies nennt man Materialhomogenisierung.
Ziel dieser Arbeit
Für die Materialhomogenisierung existiert eine Berechnungsvorschrift sowie eine voxelbasierte Implementierung in Python. Um den Materialhomogenisierungsprozess zu beschleunigen, soll in einer Machbarkeitsstudie untersucht werden, wie die Homogenisierung mit Hilfe von künstlichen neuronalen Netzen (KNN) durchgeführt werden kann und welche Geschwindigkeitszuwächse und Genauigkeiten erreicht werden können. Dazu sollen mit dem Materialhomogenisierungsprozess Testdaten zum Training des KNN generiert werden. Für die Implementierung und das Training des KNN soll auf frei zugängliche Python Implementierungen zurückgegriffen werden. Abschließend soll eine Gegenüberstellung der klassischen Materialhomogenisierung mit dem von der KKN generierten Material - in Bezug auf Geschwindigkeit und Genauigkeit - erfolgen.
Gute Programmierkenntnisse in Python erforderlich. Kenntnisse der FEM erwünscht. Tools: Python, ANSA, Meta, Abaqus
Arbeitsumfang
  • Recherche von vorhandenen und geeigneten KNN-Implementierungen in Python
  • Modellaufbereitungen von Leiterplatten und Erstellung von Trainingsdaten
  • Implementierung eines KNN mit freier Python Distribution, Training des KNN
  • Ergebnisbeurteilung des KNN generierten Materials, Vergleich zum klassischen Berechnungsalgorithmus
  • Dokumentation

Wir bieten
  • Aufwandsentschädigung
  • Umfangreiche Betreuung
  • Kollegiale Atmosphäre

Zusätzliche Informationen
Die Aufgabenstellung kann als Praktikum in Kombination mit einer Bachelorarbeit oder als Masterarbeit bearbeitet werden.
Beginn: nach Vereinbarung (Dauer ca. 5-6 Monate)
Honorar: Bachelorarbeit: €450 pro Monat / Masterarbeit €700 pro Monat
