Abstract
Deutsch: Die Verbesserung Finiter Elemente Modelle bezüglich der dynamischen Eigenschaften beschäf-tigt die Wissenschaft und das Ingenieurwesen immer genau dann, wenn experimentelle Daten diese Modelle Infrage stellen. In dieser Studienarbeit wird eine Möglichkeit untersucht, Modelle mit Hilfe eines genetischen Algorithmus hinsichtlich der Eigenfrequenzen und Eigenformen zu optimieren. Im Anschluss daran wird dieses Verfahren zur geometrischen Vereinfachung von Modellen verwendet. English: Optimization of finite element models respective dynamic characteristics is always used in science and engineering, if experimental results call the model into question. This assignment processes an approach using a genetic algorithm, which proves optimizing models concerning natural frequencies and eigenvectors. After this the process is used for a geometrically simplification of models.
