Felix Rempe: Automated Optimization of Car Parts from the Upper Interior to fulfill Head Impact Regulations using Finite Element Simulations

In the past decades the methods of structural optimization have experienced rising interest in the automotive industry. Structural optimization allows to efficiently optimize components of cars with respect to requirements such as weight, cost, durability etc. Besides the mentioned ones, requirements regarding the safety of car parts are posed by legal authorities. In the engineering process of those parts Finite Element Method (FEM) simulations are used to verify that the requirements are fulfilled. An automated optimization of critical parts promises a great benefit of time and developing costs. The present thesis describes the process of an automated optimization of an exemplary component of the upper interior: a trim covering the B-pillar. For that, the technical setup is presented and two popular optimization approaches are compared: Genetic Algorithms (GAs) and Surrogate Based Optimization (SBO). As a result, the GAs turn out to be more robust and easier to calibrate, while the SBO finds better designs in less iterations.

Florian Grötzner: Verbesserte Rekonstruktion von Signalen basiered auf bereits vorhandenen Rekonstruktionen

Ein wichtiges Gebiet in der Signalverarbeitung ist die Rekonstruktion verrauschter und verfälschter Signale. Grundlage meiner Arbeit war es, einige Methoden der Signalrekonstruktion zu verfeinern, wobei der Schwerpunkt auf solchen Verfahren lag, welche mit bereits teilweise rekonstruierten Signalen arbeiten bzw. auf diesen aufbauen um bessere Ergebnisse zu erzielen.
