    During the European Project Semester (EPS) a team of interdisciplinary students from different universities carry on a project together. The project took part with the Ignition Racing Team electric, the Formula Student team of the Hochschule Osnabrück. In particular, the work carried out during this Master’s Thesis deals with the suspension of the vehicle. In the first semester the design part took place with the Catia software. The suspension of the year 2017 was taken as a basis and the new requirements of this year were implemented, such as, the new geometry of the suspension, the new sensor of displacement and a system of adjustment of the pushrod. In the second semester the technical drawings were sent to the manufacturer and the commercial parts were bought and the building of the car was accomplished. In a parallel way, mechanical tests were performed to carbon fibre tubes for the dimensioning of the suspension. Tensile, compression and bending test were carried out to test four different CFK tube diameters. Stress-strain graphs, maximum deformation, strength and stress of the CFK tubes were calculated and compared with the solicitations of the suspension to choose the optimal solution for the suspension of the vehicle.

    FEM and modal analysis of a car body
    (2016) Azcona Goñi, Iosu; Sanchis Gúrpide, Pablo; Bahlmann, Norbert; Schmidt, Andreas; Osnabrück University of Applied Sciences (Alemania); Escuela Técnica Superior de Ingenieros Industriales y de Telecomunicación; Telekomunikazio eta Industria Ingeniarien Goi Mailako Eskola Teknikoa
    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.
