Design of Passenger Car Wheel
Kapoun, Lukáš ; Porteš, Petr (referee) ; Hejtmánek, Petr (advisor)
The present master thesis deals with the design of wheel disk for passenger car. The review part of this thesis summaries the history and development of the wheel; this is followed by a description of individual construction types of wheel disk for passenger car presently used. The construction part of this thesis provides a design of disk of given parameters based on the analysis of forces acting on the car wheel. For the purposes of design, the stress and fatigue analyses are performed.

Formula Student Vehicle Frame Optimization
Krkoška, Kamil ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The goal of this diploma thesis was to create optimalizated frame design for Formula Student/SAE. Basic requirements were, that new design must meet the newest Formula Student/SAE rules and other various requirements. In the thesis are built up an overview of most important rules and also an overview of previous frame designs. Next are described design process of the new frame and its stress analysis in FEM software. Main attention is given to analysis of torsional stiffness. The results of analysis are compared to previous frame designs and to parameters of Formula Ford. There are also given recommendations and other possibilities for further frame design development.

Mechanism of a one-cylinder spark ignition engine with elongated expansion
Tokař, Stanislav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis concentrates on the design of crank-type mechanism of engine with elongated expansion. The main attention is paid to examination of the progress of kinematic quantities and inertial forces in mechanism. Further on in the thesis, the analysis of piston-rod stress is carried out and is compared to the piston-rod of standard engine. In the last part of the thesis, there is an evaluation of advantages and disadvantages of the proposed mechanism solution.

Formula Student Pedal Assembly
Skula, Libor ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis is concerned with design of pedal box for Formula Student vehicle. Summary of design solutions is presented in introductory chapter, especially those used in Formula Student competition. Designed assembly is divided into parts of single pedals and base plate. The proposed design is supported by stress analysis of loaded parts in pedal box. In conclusion, design is reviewed in terms of the results, as well as compared with current pedal box.

Stress analysis of jet grouted shafts
Tarbajová, Mária ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
The subject of the diploma thesis is the stress analysis of the circular and elliptical shaft from material jet grouting. A new advanced constitutive Shotcrete model will be applied on the material jet grouting. In the thesis, the shaft tensile strength factor and the size of the ground pressures will be primarily examined. The practical part of the diploma thesis is completed by the comparison of the analytical and numerical calculation of the normal force of the circular and elliptical shafts.
