Stress analysis of the only extant pier of the former Ivančice viaduct
Pelaj, Jakub ; Fuis, Vladimír (referee) ; Vaverka, Jiří (advisor)
The bachelor thesis focuses on the stress analysis of the original Ivančice viadukt pillar. The introductory part describes the theoretical basis necessary for the analysis. The second part deals with the history and assembly of the bridge. The third part dedicates to the creation of three-dimensional structure which serves as a basis for conducting the stress analysis. The following part provides a detailed expanation of the solution process and analytical calculations itself. In the conclusion, the obtained results are verified using numerical calculations a supplement with partial results concerning an additional type of load.

Calculation of workpiece deflection when machining
Grebeň, Petr ; Zouhar, Jan (referee) ; Píška, Miroslav (advisor)
Selected chapters of the science branch "Elasticity and strength" applied to manufacturing of thin parts with various solution approaches. Applying theory of bars and a non-linear differential equation for the deflection line of the second order to a machined shaft. Numerical calculation in the ANSYS program. Evaluation and design of solution variants to machine thin shaft parts without supporting them.

Pneumatic cylinder
Málek, Miroslav ; Štefan, David (referee) ; Klas, Roman (advisor)
Bachelor thesis contains description and categorization of pneumatic actuators, main part is devoted to linear pneumatic motors, their design and description of individual parts of the motor with respect to its function. Part of this thesis is devoted to buckling stability of the piston rod and brief description of the parts in the pneumatic circuit. Next part of the thesis is deals with description of mathematical model of pneumatic cylinder, which results in simulation of variables describing the operation of the motor. Simulation has been done on double-acting and single-acting pneumatic cylinder with return spring. This mathematical model also includes a friction force model.
