Abstract

Bachelor thesis is dealing with analysis of torsion stiffness of the frame of Formula TU Ostrava team vehicle Vector 04. Firstly, the project Formula SAE is introduced followed by a description of technical requirements for Formula SAE vehicles and for frames of such vehicles. The thesis continues with description of simulation model for torsion stiffness analysis based on so called two-beams method. The method is based on attachment of the frame to two beams. Application of a force on one of beams causes torsion loading of the frame. Simplifications of the model are discussed and boundary conditions are applied in such manner to allow comparison of result with the experiment which is also carried out for verification and tuning of the simulation. The results from simulations and from experiment are compared together and with roll stiffness of suspension. From comparisons follows that the simulation is acceptably tuned with respect to experiment and the frame is sufficiently stiff with respect to roll stiffness of the suspension. The thesis is concluded by possibilities of optimization of the frame to increase torsion stiffness (and possibly reduce mass of the frame) and one example of such an optimization is introduced.
