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.

Bolted joint of turbocharger and cylinder head
Kolivošková, Veronika ; Píštěk, Václav (referee) ; Novák, Kamil (advisor)
The subject of this diploma thesis is the theoretical basis of the screw connection theory and the subsequent application to the specific screw connection problem. Mentioned connection is part of the turbo charged combustion engine, specifically directly between the cylinder head and the turbocharger. The diploma thesis is divided into several parts. The first part dealing with selected chapters of the screw connections and the combustion engines theory, whose knowledge is important for further chapters of this diploma thesis. The next part shows method of creating the geometric and computational model, on which were performed the appropriate sensory analyses with respect to determine the cause of the nut and bolt loose in the given connection. On the basis of the gained knowledge and their evaluation has been created a separate calculation methodology in the last part of this thesis, which describing parameters that have an impact on this undesirable phenomenon, and which should be included in analyses for similar issues. The diploma thesis was realized in cooperation with ŠKODA Auto a.s., tř. Václav Klementa 869, Mladá Boleslav, and AUDI AG, Union-Straße 1, Ingolstadt.
