Concept of Autocross Racing Car
Dobrovolný, Ondřej ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
Diploma thesis deals with the design and simulation of torsional stiffness of the frame for autocross racing car. The design put emphasis on observe the regulations of international automobile federation and the result of torsional rigidity and weight. The first part focuses on the design of vehicles for autocross and its regulations. The main part is the structural design of the frame, following with simulation analysis using finite element method and computing torsional stiffness. In conclusion, results are evaluate and referred for further development.

Stress-strain analysis of the safety frame of the racing car
Kolivošková, Veronika ; Man, Vojtěch (referee) ; Novák, Kamil (advisor)
Topic of this bachelor thesis is the recherché and following deformation-stress analysis of the race car safety cage. This thesis is divided into three parts. The first one is about the introduction of analysis itself and the FIA regulations for homologation static load tests of the race car safety constructions. The second part describes analytical and numerical approach to the deformation-stress solution of a main arch in historical formula 1 car Ferrari 1512. The outputs of these two approaches which were then compared to determine their accuracy and result verification. On this example was executed the contact analysis which was applied in the last part of the thesis. After receiving the results and conclusions from the basic example, the last part deals with the real safety frame model of Subaru Impreza Sti N15. This chapter presents the most important part of the thesis. On the model were executed three static test simulations which have to comply with FIA regulations. The task was solved with FEM modeling.

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.
