Conveyor changer
Chlapečka, Tomáš ; Jonák, Martin (referee) ; Pokorný, Přemysl (advisor)
This bachelor´s thesis contains structural design of transfer point (traverser) for europallets between roller conveyor and chain conveyor and it deals with structural design of the tweve meters long chain conveyor. The lift of the traverser is resolved by electric actuators. It is designed for a fully-loaded europallet´s to the weight of 1200kg. The thesis includes 3D model of traverser and chain conveyor, basic strength and functional calculations, drawings of the assembly.

Processing Methods of Fine-grain Materials (ECAP)
Jonák, Martin ; Man, Ondřej (referee) ; Pantělejev, Libor (advisor)
Method of equal-channel angular pressing (ECAP) is very significant SPD method whereby we are able to obtain a bulk material with UFG structure. This research deals with fundamental principles of ECAP method, an influence of the constructional design of a pressing channel and factors related to processing modes on properties of a final structure. Further, this research describes some modifications of a conventional ECAP method and processes based on its principle.
