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.

Material Handling Platform
Bábek, Tomáš ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on constructional design of workshop handling platform which is driven by linear hydraulic motor. First the types of gripping of linear hydraulic motor are described. Next part contains drafted solutions of handling platform construction. Important part of thesis is composed of statistical computing of machinery parts and their strenght computations within the frame of designed proportions. Afterwards the bearings are chosen according to thickness of shaft and the hydraulic motor and the diagram of hydraulic circuit are designed. At last controlling computations are done and assembly and weldment drawings are created.

Forks for handling logs
Seďa, Marek ; Juřík, Josef (referee) ; Škopán, Miroslav (advisor)
This master’s thesis with product design forks for handling logs as attachments for tractors Zetor Forterra the specified load capacity 1200 kg. The work is mainly focused on the design frame and fork clamps, the necessary calculations and ultimately strength check of designed structures. The work is also addressed in detail the linear hydraulic motor used for the rotational movement of the jaws, including the calculation of fork. Then there are the design calculations and stress analysis of journals. It also checked the stability of the machine. Stress analysis is performed for different load conditions and the jaw frame finite elements. As another part is making all the drawings.
