Experimental validation of active flow control concept for automotive applications
Sobotka, Vojtěch ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
Tato diplomová práce obsahuje komplexní návrh systému aktivního řízení proudu instalovaného na osobním voze Škoda Roomster. Tato práce navazuje na výzkum provedený VUT a TUB na vozidle Volkswagen UP! Návrh lze rozdělit na tři základní části - návrh spoileru, návrh závěsů a návrh vyfukovacího systému. V každé z těchto částí je návrh detailně popsán a potřebná výkresová dokumentace je součástí práce v její příloze. Pro potřeby návrhu vyfukovacího systému bylo provedeno jeho testování. Výsledky testu jsou v této části uvedeny. Práce také obsahuje komplexní popis sestavení celého systému a jeho instalace na automobil.

Technology of Production Parts solar Panels
Midrla, Zdeněk ; Sedlák, Josef (referee) ; Osička, Karel (advisor)
This work is focused on a proposal of technological production process of components of a solar panel. The proposal of technological production process is suggested in terms production series of 9000 of pieces per year. The work also contains an analysis of construction of all components of the air separator equipment. There are suggested variants of stocks for some of the components. It also includes a selection of the most favourable variant in terms of material usability and practical aspect as well. There is an technological production process designed by the chosen varinat including of a production instructions.

CNC Applications for Laser Cutting
Hruška, Daniel ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The following thesis deals with the theory of laser. In the first part, the thesis is focused on the issue of laser cutting (laser principle, cutting methods, laser division). Furthermore, the thesis is focused on basic theory of automation and NC/CNC control of machines. In the experimental part, the BUT logo was burned out with CO2 laser with the help of the company UnionOcel s. r. o.

Manufacturing possibilities of motorcycle brake wheel
Rozum, Josef ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
This bachelor thesis presents a variant solution of mass production of motorcycle brake wheel. These are part of rotating component of large diameter and small thickness made up mainly of carbon steel. The thesis presents methods for the production of unconventional machining technologies and methods of molding. As appropriate variants were selected technologies of laser cutting, water jet cutting, plasma cutting, blanking and fineblanking. The individual methods are described and evaluated their suitability for production. For fineblanking method which seems to be optimal is indicated the production process.

Unconventional Technology of Laser Cutting
Indra, Jaroslav ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis deals with the technology of laser cutting. The beginning is concerned with a general description of laser technology and laser division into basic groups. Next part refers to possible industrial use of laser beam, especially for cutting. Other chapters deal with the components suitable for the manufacture of this technology, technical preparation of production and the proposal to increase manufacturing flexibility when changing products. The last part is devoted to technical and economic evaluation.

Unconventional production technology of chains
Hostinský, Michal ; Mrňa, Libor (referee) ; Osička, Karel (advisor)
Unconventional technologies and their continual development brings along new possibilities in the manufacturing process. The submitted project is focused on solving problems in the procession of sheet metals in the manufacture of special parts of roller and conveyor chains. In the assessment of the technology of components, laser cutting was evaluated as the most optimal technology. With this goal, there was a public tender in terms of the purchase of a new machine designed for the manufacturing operations of the company of RETEZY Vamberk. This company ranks among the most major manufacturers of conveyor, roller and special chains in Europe.
