Calculation of heat and force field UniGear ZS1
Mokrý, Lukáš ; ABB, Drahomír Tůma, (referee) ; Dohnal, Petr (advisor)
The aim of my work is to describe high-voltage switchgear type UniGear 500R, which is part of UniGear switchgears family. I will focus on heating issue of one 500R unit and its parts during operation. Maximum values of this heating is limited by standards and can´t be exceed to ensure safe and reliable operation. That is why the heating tests are necessary part of designing and developing switchgears. Calculation will be made by two different ways. First is classic one-pole heating net method and second is numerical simulation in Solidworks flow simulation program. Except the theoretical description there will be presented also used 3D model and explanation of both method, used to calculation and simulation. Last point of this work is measuring of this type of switchgear and getting real data. The main point there is to compare measured values with values calculated and decide if is possible to simulate tests with appropriate accuracy. Then would be also possible to substitute the real test in laboratory, which costs many thousand crowns and takes lots hours of time. This work is collaborated with EJF division of ABB Company, where I am employed. Heating issues in this company is always on process, because of developing and improving of their products. So this work could be helpful in this field. ABB provides all materials needed, especially technical catalogues, 3D model and final values from laboratory measuring. Support from college faculty is mainly in study consultations and proposing of calculations making. In the end of work will be make final comparison and evaluation of achieved results.

The design of a mobile crawler undercarriage for transport mechine
Mareš, Michal ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
First part of this bachelor's thesis deals with the review of delta undercarriage for mobile crawlers with four delta crawler undercarriage. The text discuss the advantages and disadvantages of this approach. The second part of this work is aimed on the construction of such delta carriage with a maximum load of 5000 kg. The carriage is designed as modular to be able to be easily replaced. This basic concept was followed by precise mechanical design and the construction was supported by the basic mechanical computations of important parts. Detailed three-dimensional model of the undercarriage was performed in the Autodesk Inventor 2015 software.

Centrifugal bucket hoist
Kotačka, Petr ; Malášek, Jiří (referee) ; Jonák, Martin (advisor)
This bachelor thesis deals with bucket elevator design for transport of dry, loose and non abrasive materials according to given parameters. In the introductory chapter a short search describes the concept of suggested solution. Functional calculation, designs and checks of individual proposed equipment elements are stated in the other chapters. In the design requirements for centrifugal bucket discharge as well as miscellaneous way of filling are preferred. Appropriate drawing documentation is enclosed with this thesis.

Crawler chassis for a forwarder
Beránek, Jakub ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on using different types of caterpillar tracks with effort to minimize pressure of vehicle on forest land and keep the required speed and traction. The fractionation of undercarriage and evaluate of their abilities is provided in this work. After that, the process of deploying tracks and process of tensioning tracks is described. In the end the conceptual design of undercarriage is conducted

Bucket hoist for grain transport
Valouch, Radek ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with a construction design of a bucket elevator for grains in accordance to assigned data. In the first chapter, a conception of a proposed solution is introduced. Other chapters focus on a functional calculation, design and checking the individual components of the device. The requirements for centrifugal emptying of buckets and a mixed filling of buckets are taken into account in the design. A drawing documentation is enclosed with the thesis.

Horizontal belt conveyor
Zeman, Petr ; Pokorný, Jan (referee) ; Špička, Jiří (advisor)
This project proposes a conveyor belt for given material and transport output. A functional calculation is carried out ČSN ISO 5048 which specifies main dimensions and propulsion proposal. Based on strength analysis, calculation of shaft of driving drum is performed. Individual components of conveyor are chosen from catalogues of the companies, which are engaged in these questions, whose products are accessible in the Czech Republic.
