Drop forging of hub
Leidorf, Michal ; Kopřiva, Miloslav (referee) ; Štroner, Marek (advisor)
The Baccalaureate thesis deals with literary studies of forging. There is also processed the proposal of technology of ordered steel cog-wheel num.: BP-3-2009- 001. With regard to supposed large series of 150 000 pieces per a year, the technology of stamping on three operations at the vertical forging press LZK 4000B is chosen, the producer Šmeral brno a. s. All calculations were accomplished during the processing of the technological procedure, the following design documentation and technical-economical estimation are connected with the preceding calculations..

Calculation of thermal resistance of finned heatsink
Kyanka, Radim ; Huták, Petr (referee) ; Toman, Marek (advisor)
This bachelor's thesis is focused on the problem with analytical calculations needed to define thermal resistance of finned heat sinks. First it describes how temperature proceeds at different boundary conditions at fin tip. Than it describes different mechanisms of heat transfer, equlation of heat resistance especially of natural and forced convection. To verify the results there is comparison between analytical equlations written in Matlab program and measuring results.

The design of the recuperative heater flue gas - air
Procházka, Tomáš ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The bachelor s thesis deals with thermal-hydraulic calculation of recuperative gas air he- ater. Type of heat exchanger is shell and tube. This thesis is divided to two parts. The first part apprises the most common types of heat exchangers and their use. It contains also description about basic methods and equations for heat exchanger designing. The second part is calculation of heater with software EES. Whole calculation is checked by software HTRI Xchanger Suite. At the end of this thesis are two datasheets, whitch contains designing solutions for heater with plain tubes and solution with fin tubes. Conception of heat exchanger is chosen by TEMA Standards.

Drop forging of pinion
Kameník, Tomáš ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
KAMENÍK Tomáš: Drop forging of pinion The project has been elaborated within the framework of studies of the subject B 2307 and it presents the lay-out of the technology of the forging – the pinion which is made as the drop forging from the material 14 220. The rougher and the finishing forging die were suggested on the bases of the literature study of the drop forging. In consideration of the big series /100 000 pieces/ and the calculated forging power /25MN/ the component will be made on the vertical forging press LZK 2500P/SH (the manufacturer ŠMERAL Brno a.s.). At the end of the thesis there are performed calculations of the technical and economic evaluation.

Manufacturing of mudguard holder using forging technology
Ondráček, Miroslav ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

The conception of tail unit arrangement on aircraft
Podhorský, Matěj ; Pejchar, Jan (referee) ; Píštěk, Antonín (advisor)
This bachelor thesis provides a basic overview of empennage layout designs. It contains a theoretical introduction explaining terms necessary to understand the empennage problematics. In the main part, the most frequent empennage layout designs are described, each one with a brief description of construction, its benefits and drawbacks and airplanes with such empennage layout design.
