Production of the magnet holder
Kraval, Jiří ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
This project developed within the engineering studies of M-STG submits a proposal of a production technology of production of the magnet holder made of DC03. Based on a literary study of the problem of cutting, drawing, bending and calculations manufacturing of the component in a production die was suggested. The production die uses a normalised component and is tightened on PE 100 crank press with nominal drawbar pull 1000 kN. The conclusion of the thesis deals with the economic benefit of the suggested manufacturing technology.

Production of the valve seat
Kraval, Jiří ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
This project developed within the bachelor studies of B-STG submits a proposal of a production technology of saddle valve made of EN AW – ALMG3 material. Based on a literary study of the problem of cutting, drawing and calculations manufacturing of the component in a production die was suggested. The production die uses a normalised component and is tightened on LEN 63C eccentric press (produced by ŠMERAL Trnava), with nominal drawbar pull 630 kN. The conclusion of the thesis deals with the economic benefit of the suggested manufacturing technology.

The engine unit of forestry harvestor
Petr, Tomáš ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
At the beginning of bachelor´s thesis is description of harvester and its main parts. Then research of four six – wheeled forestry harvesters was developed. Features of compared harvesters are similar to the task. The next point was theoretical part with equations needed for calculation of rolling and inertial resistances. Based on the theory an enumeration of powers of particular driving modes was done. Then performances for work devices of harvester were calculated. From the single values were determined total powers of machine, which were transparently organized into table and graph. Based on the maximal total power were chosen three appropriate engines. From the three was selected the most suitable one.
