FEM and modal analysis of a car body

Abstract

This master thesis consists on getting a proper validation from a convertible car body model in FEM to approach later to the same real car body. To do so, we were given the FEM model by Volkswagen with all its components perfectly modeled. After understood how the software used to do this project worked, we started the comparison of our results with the results of our colleague Mr. Krampe, who was testing the real car. We had to change many di erent parameters and also the con guration of our car model to obtain some similar results. Moreover, we did a brief introduction to the modal analysis and its relation with FEM. It was the theoretical part that allowed us to understand better the results obtained.
