Design proposal of the 12U CubeSat structure
Kopecký, Matěj ; Lazar, Václav (referee) ; Junas, Milan (advisor)
CubeSat-y jsou v dnešní době velmi populární téma díky své ceně a jednoduchosti. Jejich použití se v poslední době ubírá spíše směrem ke komerční sféře trhu, kde vzniká velké množství společností poskytující široké spektrum služeb pro mise CubeSat-ů. Jednou z těchto společností je i Výzkumný a zkušební letecký ústav (VZLÚ), který nedávno zahájil vývoj série struktur CubeSat-ů o velikosti 1U – 3U. Tato závěrečná práce je zpracována ve spolupráci s VZLÚ. Práce je zaměřena na vytvoření informační platformy, zahrnující průzkum trhu a následující konstrukci včetně její pevnostní kontroly, struktury CubeSat-u o velikosti 12U jakožto pokračování v rámci dalšího vývoje série struktur o velikosti 6U – 12U.

Horizontal driven roller conveyor
Hájek, Lukáš ; Jonák, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the design-driven horizontal roller conveyor 15 m long which is used for the transport of cardboard boxes with metal material in a storeroom. A total weight of this box is 35 kg. The conveyor is functionally calculated and its main dimensions are determined. There is designed draft power, strength calculations chain, frame and strut trails. The set of drawing line, drawing section, drawing drive and manufacturing drawing sidewall are treated as a drawing documentation.

Trailer for the building machinery
Kozel, David ; Robotka, Tomáš (referee) ; Kašpárek, Jaroslav (advisor)
The aim of the diploma thesis is the structural design of a trailer designed for the transport of building machinery on roads. The structural design takes into account the legislative requirements for given category of the trailer. The thesis involves strength analysis of a trailer frame using finite element method. Based on the results of the strength analysis, structural modifications of the frame are designed and the tenseness state is calculated again. An essential part of the work is the creation of selected drawing documentation.

Design of two-stroke Combustion Engine
Kalenda, Tomáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The Master's Thesis is focused on a design of motorcycle two-stroke combustion engine. This single cylinder engine of a stroke volume of 50 ccm is based on a geometry of an existing engine of Blata company that has a stroke volume of 40 ccm. The newly designed engine contains some parts that are used in 40 ccm engine as well. This thesis contains a proposal of production technology of a cylinder as well as an analysis of actuating forces on crankshaft mechanism and solidity control of a piston and piston-rod.

The FEM analysis truck trailer HTV 18
Chalupa, Pavel ; Kumžák, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
The subject of this master's thesis is the strength analysis of the cargo trailer HIPOCAR HTV 18 and proposed modifications. For the strength analysis was selected finite element method. The frame model was modified by the results of the strength analysis. After that has been carried out the strength analysis of the modified frame.

Design of an aircraft for towing according to CS-VLA
Marek, Ondřej ; Urík, Tomáš (referee) ; Mališ, Michal (advisor)
The topic of the thesis is a design of an aicraft for towing of gliders. Based on the background research of the towing aircrafts currently used by the Czech aeroclubs and the analysis of the required characteristics of these aircrafts the design of the new airplane has been created. Moreover, the load of engine mount has been determined according to the CS-VLA directive (a certification guidelines for the Very-light aircrafts). Its construction design as well as strength calculation have been elaborated. The part of the thesis is a 3D model of the aircraft and the engine mount.

Connecting rod of aircraft engine
Vaněk, Václav ; Svída, David (referee) ; Píštěk, Václav (advisor)
This thesis describes the design layout of piston rods in a flat aircraft engine. It also includes a proposed set of dimensions of the inner and the bifucated piston rods as well as a test of forces acting on a given piston rod. The end of this work focuses on a computed strength test of the inner piston rod.
