Mobile Wood Splitter
Stuchlík, Jakub ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor´s thesis deals with the issues of the mobile wood splitter. The first part describes the basic division of splitters in the market. I am going to choose the most suitable solution for my assignment. In the second part I am going to focus on the calculation of strength and checking of chosen type of the splitter.

Proposal of technology a selected component in the control system of steam turbine
Hradil, Roman ; Osička, Karel (referee) ; Chladil, Josef (advisor)
The subject of this thesis is the design of production technology of the hydraulic cylinder – the part of servomotor of a steam turbine control valve. The main precondition is a perspective technology of manufacturing the component on a single workplace using Siemens NX10 CAM system. The implementation of this work was carried out in cooperation with the Siemen, s.r.o., the branch of Industrial Turbomachinery in Brno. Part of the thesis is a brief introduction to the issue of steam turbines. The main part is devoted to analysis of a selected component in terms of technology, design of the best strategy of production technology and its implementation. The conclusion deals with the technical and economic assessment of the proposal.

Solution technology with cutting operation of cover part
Veselý, Kamil ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This thesis was worked out on the basis of the long term experience with hydraulic cylinders of the tractor equipment for the skidding type: MA6-008. It was prepared and introduced a new production technology of the cover of the hydraulic cylinder which is modified in such a way that it is possible to use the present parts of the hydraulic cylinder. As basic material was designed the steel No.:11353. The production technology was prepared for two variants. First variant means serial production of 100.000 pieces per year out of thick-walled tube. The other variant means piece production of two parts out of the rod. It was achived reduction of the necessary time of disassembling while the lifetime of the cylinder was prolonged thanks to the new design of the cover of the hydraulic cylinder.

The process of decompression in hydraulic systems of forming machines
Havelka, Milan ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
This thesis consists of two main parts. The first part is a theoretical analysis, or a literary research, it is focused on the physical properties of the fluid, which have direct impact on the decompression. The aim of the second part is to evaluate the measurement of the forging valve and subsequently simulate the issue by means of CFD. The first simulations were performed for the maximal valve stroke and used for the CFD solver setup calibration. The subsequent analyses dealt with possible openings of the valve. In the final chapter the theoretical impact of the liquid compressibility and of the undissolved air is discussed. The results of the thesis can prove useful for the new valve setting in hydraulic circuit or for possible geometry modification.

Conception of horizontal wood splitting device
Mikl, Marek ; Hloušek, David (referee) ; Pokorný, Přemysl (advisor)
The aim of the bachelor thesis is a brief research of wood splitting machines and splitting tools, then it was the task to create own design of the horizontal wood splitting machine with the use of splitting grid according to the given parameters. The thesis is divided into four chapters. In the first chapter, the research of splitting machines was solved, in the second chapter the machine design wich was made itself, in the third chapter the strength analysis of important machine parts and in the last part the control functional calculations were made.

Wood log splitter
Růžička, Václav ; Mergl, Václav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor’s thesis is to make a brief research about wood splitters and compare their design, parameters and individual drives of these machines. In the next part of the bachelor’s thesis is devoted to the design of the machine's own concept. At first, the hydraulic circuit is designed and the hydraulic components are calculated for it, and then the splitter frame is designed. The work also includes drawing documentation of the entire assembly and frame welds.

Production Process Improvement
Majzlík, Tomáš ; Veselý, Josef (referee) ; Bartošek, Vladimír (advisor)
This bachelor thesis focuses on the analysis of the production process at HydrauliCS s.r.o., with the aim of streamlining the hydraulic cylinder production process using selected lean methods. The first part describes the theoretical background to introduce the reader to the issues of this thesis. In the second part, the product representative, the current state of its manufacturing process, and a detailed analysis of the assembly process is presented. For the analysis, the work analysis and measurement method, and spaghetti diagram are used. In the last part, suggestions for eliminating the deficiencies in the specific process and their economic evaluation are presented.

Design of hydraulic press brake
Machara, Matúš ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The thesis is focused in the first part on the issue of bending and various types of press brakes In the second part, a mechanism was designed in detail to control the ram press brake during bending. The individual situations that may occur at work have been developed. Based on them and on the theoretical consideration of the deformation of individual parts of the invented solution, the individual components were dimensioned. A possible solution of the basic construction of the whole press brake according to the assignment parameters was also outlined. Finally, a recommendation for the production of this solution was mentioned.
