Wood log splitter
Trčka, Viktor ; Novák, Tomáš (referee) ; Škopán, Miroslav (advisor)
The scope of the bachelor's thesis is to design a wood log splitter for domestic use up to a maximum diameter of the split log of 400 mm and a maximum length of 1100 mm, so that the splitting power achieves at least 120 kN. Furthermore, to create a critical research for similar splitters, to design a concept according to the specified parameters and to do the functional calculation of the splitter´s equipment and to design particular components of the splitter. Evaluation of Strength and other calculations of the main components. Equipment assembly drawing documentation and welding subassembly of the frame.

Wood-splitting machine
Bořil, Antonín ; Hloska, Jiří (referee) ; Malášek, Jiří (advisor)
The aim of this work is of known structure splitting machines to design their own structure splitting machines, including stress analysis and design of hydraulic circuit. For the design, it is necessary to select the maximum dimensions of wooden logs, which are length 1100 mm and diameter 450 mm. The machine structure is designed as a vertical.

Design of a movable lift for passenger cars
Češpiva, Zdeněk ; Láštic, Daniel (referee) ; Otipka, Václav (advisor)
This bachelor thesis deals with the design of a movable lift for passenger cars. Now we have a great deal of lifts for cars, so the research part focused on their basic division. The main parts of the work include the design of a movable lift, which is then subjected to strength calculations. After these calculations, it can be stated that the designed lift is suitable in terms of safety. The outputs of this work include drawing documentation of the assembly and selected components of the lift.

Wood-splitting machine
Hoplíček, Štěpán ; Kašpárek, Jaroslav (referee) ; Malášek, Jiří (advisor)
The objectives of bachelor´s thesis are following: Research of known designs of woodsplitting machines, comparison mechanically to hydraulically driven machines, computation and design of own wood-splitting machine. It is designed hydraulic machine with vertical structure. The machine is designed for splitting beech and oak wood with a maximum diameter of 300 mm and length of 1000 mm. It is calculated the maximum splitting force, designed and checked the frame, designed hydraulic circuit and splitting wedge. Bachelor´s thesis contains the assembly drawings of wood-splitting machine and the frame.

Vertical wood splitting machine
Zimek, Rostislav ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the analysis of wood splitting machines. Another task is to make a computational and design a splitting machine. During designing, I draw from the specified parameters, such as the clearance between the wedges 1150 mm, the log diameter 450 mm and the maximum splitting force of 160 kN. Another construction requirement is good machine mobility and vertical construction. Part of the bachelor thesis is a drawing of a splitting machine and a splitting frame together with a drawing of the support frame and the splitting wedge.

Mounting wood splitting machine
Pavluš, Martin ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The main aim of the bachelor’s thesis is to work on the design of a mounting wood splitting machine. The design of the splitting machine is based on the specified parameters. The bachelor’s thesis is divided into two main parts. The first part of the bachelor’s thesis is divided into several partial objectives. First, there is created review of woody species, including their technical parameters. At the same time, there is a recherche of known variants of wooden partition structures and design solutions. The second part of the bachelor thesis is a design of a splitting machine, strength analysis and drawing documentation.

Automatic cleaning screens for small hydro power plant
Franc, Lukáš ; Zeizinger, Lukáš (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals in the first part with use of rake screens and their distribution by relevant parameters. The first part is an overview of the different types of rake screen cleaning devices. The second part deals with the construction plan of the device, which will be placed in the entrance of a small water power plant. Further the thesis includes technical calculations which were necessary for the choice of components. Finally the last part is a strength calculation of the main parts. The drawing documentation of the device and its parts is provided as an attachment.

Hydraulic cylinder
Černý, Tomáš ; Kozák, Jiří (referee) ; Klas, Roman (advisor)
Bachelor thesis contains a brief description of the principle of operation of hydraulic motors, their use and computational relations. The main part of the research is devoted to hydraulic cylinders, their principle of function, division and construction. Also, a space for calculating the buckling stiffness of the piston rod is given. The next part deals with mathematical modeling of hydraulic mechanisms. A simple mathematical model is created in the case of a hydraulic cylinder with two identical piston rods and in the case of a differential piston. Based on the model, graphs of the frequency of oscillation are plotted. The possibilities of influencing the frequency of oscillating are explained by changing the parameters of the cylinder.
