Analysis of process for production of small plates
Talanda, Jiří ; Fiala, Alois (referee) ; Koška, Petr (advisor)
Theme of the Master’s thesis is analysis of process for production of small plates. Main parts of the thesis are analysis of the production process, process mapping, data capture, analysis of the data by Pareto analysis and find causes of nonconformities. Causes analysis is based on data analysis and process observation. It is divided to chapters by factors which are influencing the process. Optimization measures are designed with regard to their simplicity of realization and system in organization.

Effective use of 3D Cad systems in the field of process engineering-II
Marek, Tomáš ; Dvořák, Radek (referee) ; Pavlas, Martin (advisor)
The aim of this work was adoption and description of correct technigues of creation basic mechanical components under CAD system SolidWorks. This gained know ledge was then used for creation of library of standard parts used in process engineering with focus on design of pipeline systems. Conceretaly, the assembly of flouged circular Y-branch for duct system was solved. The possibility for its further modification of dimension as well as transformation into parts of similar shape was analysed. Finally, user manual describing the user interface and necessary design procedures was prepared.

The Production of the oil pan
Šupa, Jan ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The dissertation deals with a suggestion of the production of an oil pan into the car with a deep drawing. The part will be produced out of a deep drawed steel plate – class 11 305 (DC04). On the basis of a calculation and the study of the corresponding literature about the deep drawing a reverse drawing in a convention tools with a blank holder has been suggested. The part of the machine will be also an upper ejector for the fall of a sticking of a drawn part in the die. As a semi-product a blank has been chosen, which is burned out from the piece of plate with the dimension of 2500 x 12500 mm and thickness 1 mm with the help of the laser. The production quantity is 30 000 per one year. As a forming machine a universal hydraulic presser CTH 250 from the Czech company Žďas a.s. with the nominal power 2500 kN has been chosen.

Solution cutting operation of cover part.
Loukota, David ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Analysis of the typical flanged parts, constructional and functional appreciation of the single part, design of the semi-finished product and fastening of the semi-finished product, choice of machines, tools, gauges for individual operations and technological process design and time calculation of of individual operations. Economical appreciation deal with assesment of the number of machines and deal with their usage at the production, calculation of sizes process area and quantity of the workers. Final costs of tools are also solved.

The flange gasket modification of VVER 1000 pressurizer manhole
Švaříček, Tomáš ; Fiedler, Jan (referee) ; Šen, Hugo (advisor)
The main purpose of this thesis is the modification of the original flange gasket of the VVER1000 pressurizer manhole. Then the construction and function of the pressurizer itself is described, together with detailed calculations of the original and new modified gasket to meet the ČSN EN 1591 standard together with a description of the legislation that has to be followed in the calculations. The comparisons of both gasket types together with main conclusions are placed in the last section of this thesis.

Design of heat exchanger
Klučka, Ivan ; Nekvasil, Richard (referee) ; Lošák, Pavel (advisor)
This thesis is focused on the thermal-hydraulic and construction design of heat exchanger with floating head. The introductory part is dedicated to the design of heat exchangers. Next part is focused on the thermal-hydraulic design created in HTRI software (module Xist. The next section is the strength calculation of selected components of the heat exchanger according to EN 13445 in software Sant'Ambrogio. The following part describes each of the analysis in software Ansys Workbench. The final part contains complete manufacturing documentation of heat exchanger.

Suggestion of technology for flange of the pump motor
Pangrác, Pavel ; Mouralová, Kateřina (referee) ; Zemčík, Oskar (advisor)
In a study of suggestion of technology for flange of the pump motor, properties about screw pumps, features of the machined flange and the blank are processed. On the base of machinery, tools and control devices are designed. The main part consists the proposal of technological process, operating drawings and machining time calculations. In conclusion, the techno-economic comparison of the existing and future variant is done.

Technological process for part flange
Král, Zdeněk ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
In This thesis the technological process for part flange is compiled. The thesis inculdes analysis of component, material choice and choice of semi – finished product. Two technologies of production have been choosen. The production on the universal center lathe and the production on the CNC lathe. In another charter calculation times are being disscussed. Lastly the technical-ekonomic evaluation is pictured, which contains the comparison between two technologies of production.

Design of the Gear Coupling for Railway Vehicle Application
Pelíšek, Vojtěch ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The aim of this work was to create a design of a gear coupling for railway vehicle application. The work presents a comprehensive view of this issue. First of all, a brief theoretical introduction to the issue is made. The practical part follows, where the design of the whole coupling and especially the newly designed solutions are described in detail. The strength analysis performed deal with the key components that are necessary to ensure safe operation. These analyses can be applied not only for this particular case, but also to gear couplings of different designs, because in principle these calculations do not differ much. In the last chapter, which deals with the dynamic model, all the theoretical assumptions are verified, especially the coupling movements and the applied loads. If the reader deals with the issue of gear couplings, not only in the railway industry, this work presents a comprehensive view of this component. The designed coupling and all performed simulations are really usable in operation.

Production technology for mechanical seal flanges
Stoklasa, Patrik ; Gregor, Lukáš (referee) ; Zemčík, Oskar (advisor)
The bachelor thesis deals with the current technological process of the mechanical seal flange production. It contains an analysis of all tool and material equipment, the process itself and it describes selected cutting conditions and measuring aids. Variant production of technology is also characterized here, where the applied changes are described and explained in order to achieve lower costs from an economic point of view. Both variants are finally compared and evaluated.
