Students at the Faculty of Mechanical Engineering - from the Automotive Engineering, Aeronautical Engineering and Mechanical Engineering courses - have developed a new device for measuring the torsional stiffness of a CFRP monocoque as part of a project work. The CFRP monocoque is the "body" of the all-electric racing car of the Schanzer Racing Electric Team. The aim of the project work was to develop a stiff and easy-to-implement test setup. Because of the very stiff monocoque, particular attention was paid to achieving high measurement accuracy. The project was carried out in teamwork and started with the definition of requirements, the development of suitable concepts and the selection of the most suitable solution. After the best variant was selected, it was further developed and optimized using CAD and FEM methods. For the measurement of the deformations the modern optical photogrammetry system TRITOP of the company GOM was used. The optical deformation measurement allows high accuracies at any measuring points and a low preparation effort.
With the new test set-up created as part of the project, the students have made an important contribution to the Schanzer Racing Electric Team. It is already to be implemented in the next racing vehicle built by the Schanzer Racers themselves.
