Production of exhaust pipe
Frňka, Martin ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
This work introduces a design of a technology of producing an exhaust pipe. It's semi-finished product is a pipe about a diameter of 76 mm, and the thickness of it's side made of steel 11 320 is 2 mm. Based on a literary study of problematics of bending there was designed bending by minding with a ball thorn and an exterminator. The whole bending set will be fixed to a machine ELECT 150. The procesed production process includes chopping after bending on a circular saw which is followed by insertion of a complete product on a pallet.

Production of part Tube by solid forming
Grufík, Lubomír ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Propose of this thesis is designing production technology of reducing part of tube. The production of requested part is designed on the base of calculations and simulation in one operation. This operation contains widening and squeezing. There is designed on the base of calculations a tool fixed in hydraulic press ZHW 40 for the production. To prepare a semi-product is used cutting by slitting saw.

The Analysis of mutes on trombone and trumpet timbre
Košař, Vojtěch ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
This work deals with the sound mute issues, specifically how they affect the timbre of a trombone and a trumpet, their sound spectrum, levels of individual harmonic tones, the presence of formants and the directional characteristics of individual tones played in various dynamics. A part of this work is also focused on the theoretical description of a trombone and a trumpet, including their brief history, their classification, the parts they are consisting of and the timbre. The theoretical part is further dealing with the description of mathematic functions like FFT or LPC analysis, which have been implemented in the MATLAB environment when creating the graphic dependents for this theme.

Smrčka, Václav ; Buchta, Stanislav (referee) ; Bajer, Miroslav (advisor)
The aim of the thesis is to design and appreciation steel load-bearing structure of motor show. The object is situated in Brno. The Structure consist of tubes and rolling sections. The breadth of construction is 36,5m, lenght 42m and height in the heihest point is 13,2m. The structrure is consists of three parts. Show room, offices and workshop. The height of show room is 20m, offices 8,5m and workshop 8m. The show room consist of arched truss girder. The distance of each cross links is 6 m. Structural design were perfomered by Scia Engineer 2017 and hand computation.

Assessment of three types of heat exchangers
Hlavinková, Valérie ; Toman, Filip (referee) ; Baláš, Marek (advisor)
The aim of this thesis is to assess selected three types of heat exchangers designed for emergency cooling. The theoretical part of this thesis consists of a research containing an overview of exchangers. It includes a description of the construction of exchangers, characte-ristics in terms of heat transfer and an indication of the areas of its use. The practical part deals with the thermal and hydraulic design of two tube heat exchangers and a plate heat exchanger. Finally, the evaluation of the designed exchangers is performed.

Bus Station
Šotkovský, Jakub ; Hron, Lukáš (referee) ; Pilgr, Milan (advisor)
The subject of this final thesis was to elaborate variant proposal and to assess supporting steel structure roof bus station in the shape of a hyperbolic paraboloid. 2 variants were proposed, one of which was chosen as a more appropriate and this was processed details and drawings. Both variants are used as cover glass panels. Structures are made of steel with 235J0.

Influences of process parameters and material on technological forming limits of given componenet
Exnerová, Jitka ; Peterková, Eva (referee) ; Samek, Radko (advisor)
Master s thesis is focused on flaring of tubes endings. There are also mentioned theoretical pieces of knowledge which relate to tubes endings by a flat edge and a cone. The following experiments performed with the own material and tools made by the author s design. Experiments in the production of the flat collar led to the speedy rotation of the sample ending. Experiments with the conical ending brought valuable results from the point of view of comparison of theoretical and measured powers, distribution of thicknesses and utilization of the deformation web to set voltage-deformation state. The dimension excent of the conical ending was limited by the formation of buckling in the cylindrical part of the tube.

Implementation of innovative production of protective liner to the manufacturing company
Kukla, Petr ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The Diploma thesis describes the implementation of innovative production of protective liner to the manufacturing company. The liner is manufactured in sizes of nominal diameter DN 200 - DN 500. The material is low-alloy steel EN 10216-2 10CrMo9-10. For the production innovation, the technology of pipe end flaring by a movable mandrel was chosen. Verification of the functionality of this technology was performed using analytical calculations and numerical simulation of FEM. The results of numerical methods were compared with the results of a practical experiment. The experiment was performed on 5 test specimens with a diameter of 273 mm. The machine device was a hydraulic press with a nominal force of 2000 kN and equipped with pressure and position sensors. The experimentally obtained values of force and the tool path dependence were similar with the values of FEM simulation. The difference in the value of the force in the maximum tool path was 290 kN. The flared diameter was formed to a value of 319 mm. This value corresponds to 16.5% of increased nominal diameter, which is sufficient from design point of view. Non-destructive tests ruled out the presence of crack defects on the flared diameter. According the new set up working procedure was produced the first real part. Significant financial savings of CZK 3.5 - 5.3 million / year were quantified in the technical and economic evaluation. Return on necessary investments is between the 9th - 14th manufactured pieces (approx. 15% of the annual production volume). In conclusion, innovation has promising results and will be issued by the company into the production process.
