Design of transmission mechanism for Formula Student Dragon 7
Fanta, Tomáš ; Janoušek, Michal (referee) ; Svída, David (advisor)
This thesis examines the various types of transmissions which allow to seamlessly change gears without interrupting the transfer of a motor's power output. In particular, it elaborates on the advantages and disadvantages each design presents for a FormulaStudent/SAE vehicle. Furthermore, the thesis explores the selection of gear ratios and simulates acceleration parameters in order to achieve the best possible dynamic behavior. What is more, the thesis presents a concrete implementation of a transmission for the Husqvarna FE 501 motorcycle redesigned with the Zeroshift mechanism. It includes a fundamental change in the operation of the clutch as well as a gear stress analysis. Last but not least, the TU Brno Racing team incorporated the main conclusions of the thesis into the team's vehicle in order to improve the team's standings in international races.

Modeling of Exhaust Manifold for Turbocharged Engine
Fanta, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
This work describes different structural designs of the exhaust manifold and creation of parametric models of exhaust downpipes of supercharged engine 1,4 TSI. Next, the study deals with exhaust manifold’s materials and with present basic principles of thermodynamic and hydrodynamic. Then two parametric models were modelled in Solidworks software. First model was made according to existing exhaust manifold of engine 1,4 TSI. It was symmetrical model (collector in the axis). For second parametric model the collector was moved in horizontal direction, so this model is asymmetrical. Both models were evaluated considering their complexity of structural design and their manufacturing claims. Finally the possibility of CFD analysis for evaluation of parametric models was studied.
