Strain, stress and safety analysis of the car reinforcement frame
Dobeš, Martin ; Vosynek, Petr (referee) ; Vrbka, Jan (advisor)
This master thesis deals with the strain, stress and reliability analysis of the safety frame of racing car. The safety frame is a part of passive safety, which it becomes active in a case of impact. The safety frame makes a reinforcement of the car body and provides its sufficient stiffness. The first part of the master thesis is focused on determination of stress and strain states during the static loading tests and their analysis. The loading conditions are prescribed by homologation regulations of Fédération Internationale de l´Automobile (FIA). The problem is solved, making use of computational modeling utilizing the Finite Element Method (FEM). The first part of thesis is used for the stiffness and safety analysis under the static loading test. The second part deals with the effect of loading velocity on the stress and strain states using the computational modeling and solver LS-DYNA.

Electric Off-road Vehicle for Children
Dostálová, Adéla ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The master’s thesis focuses on the design of an electric off-road vehicle for children, the concept of which is based on racing buggy. This vehicle will be power by an electric motor. The output of the work is the overall conceptual design, structural design og the safety frame and accessories. The safety frame will undergo a homologation test. The design of the buggy is subject to a price estimate.
