Svoboda, Tomáš ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
Diploma thesis deals with design of crankshaft for two stroke opposed piston diesel engine. In the theoretical research part a history, comparison with competitive engines in nowadays light aircrafts and the advantages of opposed piston engines are mentioned. In the practical part the balancing is chosen and CAD model of crankshaft is designed. Geometry of this model is than checked for fatigue damage fallout. In the final part was chosen the propeller and appropriate reduction gearbox.

Svoboda, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The subject of the diploma thesis is the design of the ghrinder bridge over the Kyselá voda brook valley. The main topic is static calculation of supporting construction of six span structure. Two studies were executed and the second option, pre-stressed girder bridge was chosen. The lenght of the spans is 27 + 6 x 35 + 27 m. Static model and effect of loading are solved in software Scia Engineer. Reviews are calculated by hand according to current standards.

Titania suspensions for material printing
Svoboda, Tomáš ; Drbohlavová, Jana (referee) ; Dzik, Petr (advisor)
This bachelor‘s thesis deals with the preparation of stable suspensions of titanium dioxide applicable for material printing. A wide range of dispersive environments stabilizing the nanoparticles of titanium dioxide was investigated. Commercially available aqueous dispersion and dry titania powder was used as the source of TiO2.The properties of prepared suspensions were evaluated and the most suitable suspension was used for material printing. This thesis focused on suspension‘s stability, sizes of particles dispersed in them, and in their rheological behavior. Furthermore, we analyzed the studied the properties of printed layers by SEM, optical microscopy, DLS and analytical centrifuge. We also evaluated the photocatalytic activity by monitoring the oxidation rate of coumarin to 7-hydroxycoumarin.

Design of mobile chipper
Svoboda, Tomáš ; Šuranský, Michal (referee) ; Brandejs, Jan (advisor)
The Bachelor thesis deals with the structural design of a mobile chipper that uses mass-produced compact tractors VARI as its energy sources. This Bachelor thesis is divided into four main chapters: a description of the basic technology used for processing natural materials that is characteristic of this type of equipment, the current state of structural details of compact tractors VARI and their equipment, a detailed study of technical aspects of the compact tractor providing the power, various drafts of possible solutions with a presentation of a functional home-made prototype, and a detailed description of the final version of the design. The thesis also includes an approximate calculation of the maximal possible diameter of the processed material and a technical drawing.
