Napjatostně deformační analýza mostu v Třineckých železárnách
Ščerba, Bořek ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis analyses stress and deformation of the truss construction. The first point of the thesis is a research, which includes obtaining information about the construction, for exemple dimensions, loads, purpose, history etc. Then, calculation models are created considering a different level of simplification. Two analytical models are crutial for the thesis – one statically determinate and the other statically indeterminate. They are used for analysing two different loads applied to the construction using methods of solid mechanics – it’s own weight and its own weight in combination with a weight of a vehicle that is driving through. Afterwards, the statically inderteminate model is verified using finite element method (FEM).

Simulation of Effects of Short-circuit Currents in HV Switching Stations
Tománek, Miloslav ; Buriánek, Jiří (referee) ; Toman, Petr (advisor)
This thesis is engaged in a theoretical calculation of short-circuit currents in electric power system in compliance with the norm ČSN 60909-0 and first of all with calculation of dynamical and thermal effects of short-circuit currents in HV switching stations in accordance with the norm ČSN 60865-1. Next the thesis is engaged in a production of programs for simulation of mechanical effects of short-circuit currents with respect to a dimensioning of constructional elements of switching station and afterwards in a practical simulation of selected parts of the real switching station type „H“ in Slavkov u Brna.

Steel structure for the the stationary hydraulic unit
Petr, Tomáš ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
The main theme of this diploma thesis is a description and a strength analysis of several steel structures of valve frames used by Bosch Rexroth, s. r. o. The first part sums up possibilities of fastening of hydraulic control elements. Furthermore, current types of valve frames were described. The strength analysis of three steel structures was output of using the finite elements method. The result of these analysis was the determination of the loads and critical points of individual structures. In the end of this study, new structures for one block frame were designed to modify the critical locations of the original solution.

Design and optimization of tractor front drive axle console
Šincl, Josef ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The master thesis is about design and optimization of tractor front drive axle console. The first part, include the design of the new console geometry with respect of the surrounding area. After that is on the newly designed part performed a strain-stress analysis for three selected operating modes of the tractor, which have been defined based on critical operating situations. In thanks of the results of the individual states, the geometry of the component is adjusted according to meet the fatigue failure limit state. After inclusion of critical site modifications, the console design was subjected to design optimization in the ANSYS Workbench program to reduce the amount of material by 10%. The end of the work, is carried out the evaluation of these places and then the console control calculation.

Svoboda, Marek ; Foretník, Jan (referee) ; Kristek, Jan (advisor)
Spas are designed on the principle of stage and auditorium, where the visitor becomes either actor or observer; actor or spectator. Fragmenting each "act" active activities through a carefully programmed observation sites and vistas is needed to create tension between actor and observer. "Story" is is revealed gradually, and his understanding is necessary to move the proposed space and rotate each "Auditorium". Achieve a comprehensive sensation viewer is associated with the need to crawl space spa. Act is repeated. From the viewer becomes an actor and the actor spectator. The body is in motion and mental marches are a reflection of observation of physical events. (google translator)

Torsion of beams with a non-circular cross-section
Hablák, Ján ; Majer, Zdeněk (referee) ; Profant, Tomáš (advisor)
The bachelor’s thesis focuses on the issue of torsion of prismatic bar with a non-circular cross-section, its model in various software, calculation and comparison of real measurements with calculated values. The aim of the work is to get acquainted with the basic theoretical knowledge, which will subsequently be applied in the modeling and calculation of specific closed profiles. Individual results are compared in the thesis. Basic concepts and knowledge are explained in the theoretical part. The practical part deals with the calculation of individual cross-sections and practical measurement.

Collection of solved examples from Elasticity and Strength
ŠIMANOVÁ, Petra
The thesis is designed as a brief teaching text for the course Technical Mechanics II at the Faculty of Education of the University of South Bohemia in České Budějovice. The topics included in the thesis are simple tension, simple compression, simple shear, simple bending, simple torsion, buckling. The theory is supplemented by examples with annotated solutions for each type of stress. The thesis also contains several complex problems on dealing with multiple types of stresses on a structure. The work can be used by teachers of the subject in preparation for classes and by students in self-study or in preparation for various examinations or tests.
