Determination of electromagnetic field distribution around underground power cable
Gromotovič, Ivan ; Paar, Martin (referee) ; Vyčítal, Václav (advisor)
The thesis deals with the distribution of the electromagnetic field around the conductor in the way of laying the conductors. The paper describes the structure of the cables and their lettering. More detailed is described the underground cable and various ways of protecting the conductor against mechanical damage are shown. The functions of the locator of underground lines on the electromagnetic field principle are briefly described . In the practical part, in simulation software Ansys Maxwell has been designed models to simulate the layout of the underground line. The output of the thesis is the comparison of the results created by the simulations.

Measurement of vehicle moments of inertia
Grác, David ; Hejtmánek, Petr (referee) ; Porteš, Petr (advisor)
This diploma thesis is concerned with selecting the appropriate method for determining the moment of inertia to the vertical, lateral and longitudinal axis through the centre of gravity of the vehicle. Using the special mechanical device, constructed on IAE was carried out repeated measurements of known mass properties in each axis. With the aid of obtained data was calculated measurement error. To compare the resulting values was created MBS model.

Production of pinion by solid forming
Fic, Pavel ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
In a present diploma thesis is detail study from volume hot-forming knowledge – forging. In thesis is make proposal of technologies how to produce a pinion d140 drawing nr.: DP2012 -01 and the optimatization of technology procedure with help a computer simulation. Quality of part is steel 14220. Semi-product is a bar 80 x 150 ČSN 42 5510.21. For presumtion series 160 thousand pieces and mechanical stressed working of piece is choose drop forging technology in the vertical forging press LMZ 2500, product of Šmeral Brno. From technical procedure were made necessary calculations and follow drawing documentation.

Optimization of the Wire Drawing Process
Kabilka, David ; Světlík, Radim (referee) ; Řiháček, Jan (advisor)
The aim of work is to present and analyse assessment of the current state and at the same time the proposal of adjustments to the technology or parameters, the introduction of the wire into the drawing machine. The problem arises when the introduction of wire with a diameter of 14 mm from the material CK 67 to the drawbenches Schumag. If we introduce the wire into the drawing machines with two primary beams leads to a buckling of the wire and pack between the drawing die and the boot device. For the introduction of wire are used hydraulic boot collets, which are controlled semi-automatically. In connection with professional studies and on the basis of the calculation, simulation and practical experiment have been identified the conditions allowing the current method of deployment of wire to use.

DISCONNECTOR PARALLEL CURRENT PATHS OPTIMIZATION
Görig, Tomáš ; Tůma, Jan (referee) ; Dohnal, Petr (advisor)
The objective of this master´s thesis is diagnostic the actual disconnector current path that is unevenly stressed by nominal current. The most stressed parts are excessively heated. In next part are projected a few options to optimize the current path. The options are verified by simulation. The best option is recommended to the submitter.

Design of the robotic work cell for the spot welding
Hrubeš, Kryštof ; Szabari, Mikuláš (referee) ; Bražina, Jakub (advisor)
This work deals with the design and creation of a virtual simulation of a robotic workplace for spot welding in the Tecnomatix Process Simulate. The aim of the work is to get acquainted with the issues of robotic workplaces, especially in the field of spot. Then, based on this knowledge, design a robotic work cell for welding two sheets. The whole process will then be simulated in the Tecnomatix Process Simulate and this simulation will serve as a demonstration in teaching.

Design of urban area using advanced technologies
Nováček, Michal ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
The subject of the thesis is to define sunlight illumination as a building-influencing physical factor from the perspective of the technical standards in the Czech Republic. It aims to optimize the draft making process, and a quality of selected technical standards for sunlight illumination in the Czech Republic. In conclusion there is an example of a sunlight illumination analysis in different ways.

Design of Tool for Louvers Production
Hejna, Jaroslav ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This thesis presents a tool design for production of embossments into the bottom part of the agricultural silo made of Dx51D material. The research analysis all technologies used for embossing, that is cutting and shallow drawing. This is followed by a chapter on simulation. The tool design itself is described. Its principle is based on tools for punching machines. The upper half of the tool is composed of a weldment to be clamped into pressing machine, into which are mounted functional parts in the form of inserts. The lower tool consists of several bolted plates, punches and a holding plate, which is located on the springs. In order to achieve correct design, necessary calculations were carried out and it was all confirmed by simulation in ANSYS. The two tool halfs are guided by pins attached at the edges of the lower tool. The technical - economical evaluation compares the work of the proposed tool with other possibilities of embossing.
