Wood-splitting machine
Henzl, Lukáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
The thesis describes the design of the wood-splitting machine including stress and check calculations and design of the hydraulic circuit. For structural design, it is necessary to choose the maximum dimensions of wooden logs, which have length 1,1 m and diameter 0,5 m and over. The machine structure is vertical. Another task of the thesis is a technical report of similar machines and the justification of the design concepts of splitting machine. In the thesis, there is elaborated an experiment on different types of wood splitters, stress analysis calculated by using finite element method and there is also drawn up technical parameters of wood.

Design of Conveyor Semi-Trailer
Nepovím, Ondřej ; Kovář, Stanislav (referee) ; Pokorný, Přemysl (advisor)
The first part of the thesis focuses on a research study of high-strength steels. The thesis also includes a conceptual design of the supporting structure of a transshipment trailer, which uses high-strength materials. This design is compatible with the Herkul trailer produced by the company NovaSteel s. r. o. and distributed by the sales network of Romill Brno, spol. s r.o. In its final part, the thesis deals with a stress analysis of the proposed design of the transshipment trailer. Stress-strength and deformation tests were carried out by means of the finite element method.

Rail undercarriage of stacker/reclaimer
Schűssel, Jiří ; Krása, Jakub (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with rail undercarriage of stacker/reclaimer used in thermal power plants. The paper focuses on a conceptual framework of two-track bogie rail undercarriage and on a calculation of maximal load of undercarriage wheels within operational processes. The results are used for a design of two-wheel driven bogie and its main parts. The next part of the thesis presents finite element method analysis of a designed bogie along with a projection drawing. The diploma thesis was elaborated in cooperation with a company NOEN a. s.
