Simulation of the trencher device prototype
Polák, Václav ; Sommer, Matěj (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis were a simulation and an analysis of the construction of a prototype of additional trencher equipment. At first an analysation of a prototype and a calculation of load states was made. A simulation was made in a multi body system in program MSC Adams View. According to load states was made a stress analysis in program MSC Apex Jaguar. All acquired results were analysed and according to them changes were made to the frame construction. Part of this thesis contains drawings documenting.

Sheeting of Foundation Pit
Vodáček, Ondřej ; Chalmovský, Juraj (referee) ; Glisníková, Věra (advisor)
First part of the thesis talks about pit sheeting in general, including shafts and trenches as well as pits, however pits are the very main topic and therefore described in details. This part also discusses earth pressure and groundwater issues as applied loads, yet only marginally. Second part demonstrates a particular sheeting structure and its calculation. All presumptions are established here, including double-anchored sheet pile wall geometry, spoken earth pressure loads and groundwater loads plus heavy equipment load during a construction. The calculating process is shown using computer softwares (Plaxis 2D, GEO5) and also in a non-software way using just pen and paper. At the very end of thesis an ultimate limit state (ULS) of sheet piles is assessed, software and non-software results are compared to each other and discussed.

Trencher attachment for a earthmoving machine
Polák, Václav ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the possibilities of creating a deep groove. The search part contains an overview of similar devices offered, including the relevant skid steer loaders. It also deals with safety requirements and legislation. The main part is devoted to the actual design of additional grooving equipment, including calculations of key elements.

Analysis of Trench Insulated Gate Bipolar Transistors
Karlovský, Juraj ; Polčák, Josef (referee) ; Bábor, Petr (advisor)
This thesis is focused on the selection and optimalization of suitable analytical methods for study of TIGBT (Trench Insulated Gate Bipolar Transistor) structures with a use of methods, that depict material composition of the studied sample. The theoretical part contain explana-tions of the analytical methods used for measurements and basic principle of operation of an TIGBT transistor. The practical part contain the methodic of measurements and the evaluation of the obtained data and design of optimal procedures in done experiments.
