Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.

Alternative conceptions of combustion engines
Šťáva, Martin ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
The subject of this bachelor´s thesis on the topic Alternative conception of combustion engines is description of chosen historical and present alternatives to conventional piston combustion engine with crankshaft. The aim of this thesis is to create thesis that relates description of historical evolution of alternative construction combustion engines. Alternatives are described in terms of construction, operating principle and properties. In past were developed plenty of different conceptions of combustion engines. However most of them have never been successful because of many technical problems, complicated construction or other shortages.

REINFORCED CONCRETE CYLINDRICAL TANK
Chumová, Petra ; Podroužková, Božena (referee) ; Šulák, Pavel (advisor)
The Bachelor´s thesis focuses on a static solution of reinforced concrete cylindrical tank. The thesis comprises dimensioning of the bottom of the tank and its walls to selected load cases and processing a drawing documentation. The calculation of internal forces is done using the software Scia Engineer. The validation of results is performed by hand calculation using differential equations on a simplified model for the results of internal forces in the wall of the tank.
