Design of Modern V8 Combustion Engine
Šebesta, Radek ; Drápal, Lubomír (referee) ; Svída, David (advisor)
Master´s thesis is considered with design and construction of V8 combustion engine with small size and low mass of its body. In the construction were used mass-produced components from the other engines. From every component was generated a 3D model in computer program Pro/Engineer, new necessary parts were made in the same program and put together to assembly. Main part of the construction was to design a new crankshaft, a crankcase and an engine lubricating system. The crankshaft was subjected computing analysis in program Pro/Mechanica, using FEM.

Six-cylinder in-line diesel engine with cylinder deactivation
Novosád, Ivan ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
Master 's thesis deals with design of a drivetrain of six cylinder inline engine with cylinder deactivation for heavy agricultural vehicles. In this thesis were devised various possibilities of crankshaft balancing, the best design solution of counterweight was based on optimization in software Catia. Further, the crankshaft was analysed for force and momentum loading and torsional vibration, based on which, the torsional vibration damper was designed. There were considered several options for cylinder deactivation, which were analysed for finest run of engine and the best thermal distribution. Based on these criteria, the best option was to deactivate 2nd and 5th cylinder. The crankshaft was analysed for the fatigue failure by finite element method. The fatigue failure is the most dangerous case for the crankshaft, the resulting safety factor for this limit state is 3,05.

Hinged adapter of corn header
Řezníček, Milan ; Fajmon, Petr (referee) ; Pokorný, Přemysl (advisor)
The master’s thesis contains a plan of hinged adapter for cord header Cornpower 8-75 of the BISO Schrattenecker Company. The adapter is designed for threshing machines New Holland. The thesis includes a comparison of the mechanisms used by competitors. Further it contains design of the entirely different mechanism, its kinematics solution of the hydraulic circuit and calculating of the strength using FEM method, including calculation of contacts. The drawing documentation is done in Catia V5 and strength calculations in NX-Ideas and Marc 2010.

Piston for SI Turbocharged Engine 2.0L
Kusyn, Petr ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis is focused on solve of design solutions for piston for turbocharged version of Honda K20A engine, especially on reduce of side force acting on piston. There are mentioned methods and on their basis also design solutions for piston to reduce this force. There is also included kinematic and dynamic analysis for each solution and as well their FEM analysis for testing the suitability of these solutions.

Analysis of frame of road bicycle
Šustr, Dominik ; Hloušek, David (referee) ; Pokorný, Přemysl (advisor)
This bachelor's thesis deals with the FEM analysis of the stiffness of the REPETE R2: REASON road bike frame according to the stiffness testing methodology in EFBE laboratories. The theoretical part describes the most important facts about the design of the analyzed frame and the history of brands that are important for the frame. The empirical part then summarizes the results of the FEM analysis, thanks to which we revealed the area around the bottom bracket as the weakest structural point of the frame, which can have a negative effect at higher loads. It probably also makes more sense to orient the pipe cross-sections horizontally.

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.

Design proposal and analysis of the 3D printed 1U CubeSat frame
Kilián, Ondřej ; Jetela, Václav (referee) ; Lazar, Václav (advisor)
Tato diplomová práce se zabývá tvorbou a následnou analýzou 3D tisknutého rámu pro satelit třídy CubeSat. Tento CubeSat je konstruován podle standartu „CubeSat Design Specification” z Kalifornské polytechniky revize 14. Unikátní přístup, jakožto použití 3D tisknutého plastu je bude potřeba podrobit následným reálným testů které nejsou v rámci této diplomové práce, jelikož použití 3D tisknutých plastů není zahrnuto v tomto standartu. Modelování a tvorba podpůrných materiálů pro generaci G-kódů a pro následnou MKP analýzu je provedeno v programu Autodesk Inventor Pro 2020. Tyto podpůrné materiály jsou ve formátu STEP. G-kódy pro 3D tisk jsou tvořeny v programu PrusaSlicer 2.4.1. MKP analýza je provedena v programu MSC Patran a MSC Nastran kde generace sítí, zavádění sil a umístění okrajových podmínek je použit program MSC Patran. Následná řešení je provedeno v řešiči MSC Nastran a poté interpretace výsledků je provedena díky vizualizacím zpět v programu MSC Patran. Celkový design je považován za úspěšný, jelikož splňuje veškeré požadavky na něj kladené a zároveň je adekvátně zkonstruován, aby vydržel zatížení na něj kladené během vypuštění na oběžnou dráhu kolem země.

Powertrain of five -cylinder gasoline radial engine
Vítek, David ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This Diploma thesis deals with a design of a powertrain of fice-cylinder gasoline radial engine with assigned main parameters (bore, stroke, etc.). The work is divided into several parts: kinematics of the radial engine, creation of 3D models, force acting on the connecting rods, balancing of the engine. The last part is focused on creating MKP models, stress analysis and determining of fatigue safety of the selected parts.
