Loss and Heat Calculation of Oil Transformer Top Cover Near Bushings
Trombik, Šimon ; Toman, Marek (referee) ; Mrajca, Miroslav (advisor)
This bachelor's thesis deals with the calculation of losses on the cover of an oil transformer in the vicinity of LV bushings. This is because there is thermal stress and aging of the seal under the grommet and, subsequently, oil leakage. The production of oil transformer sub-parts is briefly described here, and the chapter is devoted to transformer grommets. Another part is also a literature search of eddy losses in the cover and container of the oil transformer. Subsequently, the preparation of the electromagnetic and thermal simulation is described here, where a lot of attention was paid to heat in particular.

Technology of production parts by forming
Litochlebová, Soňa ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis solves the efficient production of the sheetmetal cover. The new technological procedure will save two manufacturing operations deep drawing. The deep drawing of the cylindrical vessel with a flange and its following calibration in accordance with the design documentation was choosed. The last stage of the deep drawing is the construcion of the circular cut-out and its bending. By doing so the final shape of the cover will be reached.

Design of forming tool for production of cover
Běhal, Petr ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The Bachelor work presents the project of shanking tool for cover pro producing. The cover is made from deep drawing zinc coated steel sheet DC05 + ZE 25/25 numbering about 100 000pc per year. Procedure of production is solved by sequence drawing from strap. The result is documentation of sequnce combined shanking tool.

Solution technology with cutting operation of cover part
Veselý, Kamil ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This thesis was worked out on the basis of the long term experience with hydraulic cylinders of the tractor equipment for the skidding type: MA6-008. It was prepared and introduced a new production technology of the cover of the hydraulic cylinder which is modified in such a way that it is possible to use the present parts of the hydraulic cylinder. As basic material was designed the steel No.:11353. The production technology was prepared for two variants. First variant means serial production of 100.000 pieces per year out of thick-walled tube. The other variant means piece production of two parts out of the rod. It was achived reduction of the necessary time of disassembling while the lifetime of the cylinder was prolonged thanks to the new design of the cover of the hydraulic cylinder.

Solution turning technology of part "víko" with coated cutting tools
Prokop, Karel ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
In this bachelor´s thesis is processed analysis of part called cover and there is also processed proposal of the technology its manufacturing. Into proposal of manufacturing are included conventional tools which are compared with different type of manufacturing by tool called EcoCut. For both varieties is elaborated technological process, instruction for turning with counted mechanical times and consumption of changeable cutting tips.

Alternative designs for removable connection with cover and housing of airbox
Dvořák, Milan ; Fejta, Tomáš (referee) ; Škopán, Miroslav (advisor)
The aim of this thesis is to description and comparison of solutions, demountable connection of the lid and box enclosure air filters for motor vehicles, developed and used by the manufacturing concern MANN + HUMMEL, for which air filtration only one part of a broad portfolio of filtration systems for the automotive industry in the world scale. Another part of this thesis will be one of the chosen optimization methods of connection and implementation of alternative proposals design solutions, including the selection of the best solution, creating design calculation, 3D design, FEA analysis and prototyping of an alternative connection method laser sintering. When creating the optimization and design of alternative design solutions can count on the possibility that existing solutions are taking all possible factors and that the best alternative design proposals show an improvement over existing at the expense of all other cells throughout the development of the product.

Alternative designs for connection with cover and housing oil module
Svoboda, Vít ; František, Ondřej (referee) ; Škopán, Miroslav (advisor)
This diploma thesis describes the design of new connections and modification of existing connections cover and housing of oil module for trucks. This connection must resist the effects of operating oil trucks modules. These effects include pressure pulsation, temperature fluctuations, vibrations and weather conditions. The most important is the resistance of cover to rotation and loss of tightness. The work includes research of different connections usable for this application. Other research focuses on the use of connection of other manufacturers in the market. The work included a proposal of possible solutions for the modification of cover and housing and their evaluation using specified criteria with rating matrix. The final part deals with the development of the three best evaluated proposed solution. For each solution is made as necessary calculations, drawings and next steps of implementation of individual solutions.
