DC electronic load
Pavloň, Martin ; Kapinus, Tomáš (referee) ; Havlíková, Marie (advisor)
This document deals with description and measuring on the electronic loads, also describes user interface, working modes and electronic protections. Compares technical parameter of individual electronic loads. Discuss differences between resistive and electronic loads. Propose method to verify static and dynamic load. In the last part it deals with measuring on the electronic loads, according to proposed methods and with processing of measure data.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Safety factor evaluation for an out-of-plane frame under static loading
Málek, Michal ; Profant, Tomáš (referee) ; Burša, Jiří (advisor)
This bachelor thesis deals with evaluation of safety factor of a space frame when being statically loaded. This examination was demonstrated on a particular example. In order to solve the above mentioned, we exploit the frame symmetry. Unknown parameters were identified from deformation conditions in the point of intersection of the symmetry plane and the frame centreline, where the shift and two turning angles equal zero, and further by means of Maxwell- Mohr variant of Castigliano's theorem for determination of the frame deformation. The basis for calculations of stresses was represented by the theory of combined bar loading, particularly combination of bending and torsion. When examining the frame safety we took into consideration mainly dangerous points possibly occuring through cranks and fixed supports, where stress concentration occurs. The results of analytical solution were verified by numerical calculation in program ANSYS 10.0.
