System for Exhausting of Combustion Gases over the Sintering Grate
Kratochvílová, Silvie ; Nohál, Libor (referee) ; Dvořáček, Jiří (advisor)
This bachelor thesis deals with solution for waste gases exhaustion system above the sinter grate. The first part is dedicated to the general treatise about sinter grate, its operations and individual modifications. Another part looks into issues covering placing of the cover above the sinter grate. Proposal of optimal solution of the waste gases exhaustion system is done in last part, where are described reasons, which lead to its choice.

Construction of single-purpose machine for grinding bricks LI CRETE
Hubálek, Tomáš ; Dzimko, Marián (referee) ; Dvořáček, Jiří (advisor)
The aim of this thesis is to design a one-purpose machine for grinding concrete light-permeable bricks LiCrete. The bricks LiCrete are a new interior design component. The final step of manufacturing is wet grinding with high quality and accuracy. At the same time it is grinded the concrete and light-permeable parts made by polymethylmethacrylate (PMMA). It is important to keep size and quality appearance of the bricks. The research part contains description of the problems related to the grinding of the bricks LiCrete. The next part is about conceptual variants of the solution. The construction contains the complex solution of one-purpose machine with technical drawings. The last part include a conceptual design of continuous high-productive machine for grinding LiCrete bricks.

Development of a New Generation of Devices with Advanced Diagnostics for Determining Contact Degradation
Dvořáček, Jiří ; Hájek, Karel (referee) ; Náhlík, Luboš (referee) ; Pazdera, Luboš (referee) ; Mazal, Pavel (advisor)
The thesis proposes a methodology for damage identification of thrust bearings using acoustic emission method. The work is the way of the hydraulic loading of specimens and thrust bearings with programmable settings severity and duration of load cycles during contact fatigue tests at stations Axmat. They are designed structural adjustment elements (waveguides) to capture the acoustic emission signal selected apparatus, including the modification of software to capture the data. At the described experiments is verified functionality of the circular test specimens and axial bearings . Part of this work is to propose a new methodology for identifying early stages of contact fatigue using a combination of diagnostic methods.

Desk for splitting semiautomatic
Jurák, Pavel ; Vlašic, František (referee) ; Dvořáček, Jiří (advisor)
The subject of the bachelor thesis is the design of the working table, which will ensure the stem lifting and its transport to the splitting semi-automat. Lifting of stem with weight up to 500 kg is ensured by lifting arms. Then, the stem is moved to the splitting semi-automatic by means of a belt conveyor. The design of the frame is designed to withstand a load of 5000 N. The lowest security has k = 1.2 according to the strength analysis. The table frame can be easily folded using a hydraulic cylinder. Thanks to this we can easily mount the frame behind a splitter semi-automatic and transport both devices at the same time.
