Rolling Analysis of Turbocharger Pin Roller
Pazour, Martin ; Žatko, Miroslav (referee) ; Novotný, Pavel (advisor)
The subject of the diploma thesis is a description of movement of a roller which is a part of turbocharger. The diploma thesis is created in cooperation of the research department of Honeywell in Brno. The thesis consists of review concerning operating of turbochargers and possibilities of solving contact problems. Then static and dynamic conditions in contact are treated in the following part. Contact pressures are generated using numerical simulation in Ansys software. In the conclusion sizes and coefficients of friction which are recommended as the most suitable to achieve minimal wear of the components in contact.

Roofed Footbridge
Janírek, Karel ; Buchta, Stanislav (referee) ; Barnat, Jan (advisor)
The content of the master’s thesis is a design and evaluation of the timber construction of roofed footbridge for pedestrians and cyclists across the river Bělá in Jeseník in two different options of structure. The final version is solve in detail. It is a bridge with a span of 32 m and width of 4 m. The supporting structure is made of two two-hinged arch of glued laminated timber with lower deck and steel suspender. The bridge deck consists of two main girders, cross beams and stringers. Roof is from arches, roof beams, steel columns and cross beams. The stability of the whole construction is provided with horizontal longitudinal bracing in the plane of the deck and in the plane of the roof. The calculations are processed according to Czech technical norms ČSN EN.

Piston for Racing Engine Škoda 110
Gerák, Jakub ; Maršálek, Ondřej (referee) ; Svída, David (advisor)
This Bachelor's thesis deals with the defect of the piston Metalex for a racing engine Škoda 110. The aim of my work is to find the reasons for the piston defect, to check the most stressed parts by strength calculation and suggest a possible structural design so that the piston withstands all stresses throughout the required lifespan.

Arrangement of Piston for BMW 2,5 TDS 4-stroke CI-engine
Rada, Lubomír ; Drápal, Lubomír (referee) ; Svída, David (advisor)
In this bechelor work presentation and design a four-stroke piston diesel engine with direct injection diesel by 130 kW, which is used in BMW vehicles. When choosing key dimensions come out of the original dimensions of the piston, used in diesel engine with indirect injection into the vortex chamber 105 kW of power. The draft of the main dimensions of the piston followed by strength calculation of the critical points of the piston.

Piston for 80kW 4-stroke CI-engine
Vostrejž, Jan ; Dundálek, Radim (referee) ; Svída, David (advisor)
This bachelor thesis deals with a piston design for a four-stroke spark-ignition engine with the power of 80kW. The aim of this thesis is to determine main proportions of the engine, the piston, the crank mechanism and to perform a solidity check of the critical piston crosscuts. The thesis also contains a design documentation of the piston for the spark-ignition engine.

Piston for 147kW 4-stroke SI-engine
Hejda, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the design of piston for 147 kW 4-stroke SI-engine, which is used in Octavie 2,0 TFSi RS. The work is focused to main dimensions of the piston, to make it able to work in difficult, temperature and strength conditions as exposed to in its lifetime. One of the most important part of design this piston is strength calculation.

Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.

Two-speed gearbox
Kratěna, Jan ; Pokorný, Přemysl (referee) ; Ždímal, Pavel (advisor)
The objective of this work was to create the „Technical Documentation of Two-Speed Transmission“. The submission included a brief content of the demanded work. At first, calculations of gear ratio, tooth system dimensions and module were performed. Subsequently calculations of single tooth wheel loads and their safety were performed. After the tooth system calculation the shaft, bearings and key calculations followed. The Technical Documentation was completed with pictures and charts that illustrate the individual load points. A 3D model of the two-speed transmission inclusive detailed drawings of the individual shafts and tooth wheels were created as a part of the documentation as well.

Steel structure of training tennis hall
Vlček, Radek ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The content of the bachelor thesis is a proposal and evaluation of a steel load-bearing structure of a rectangular tennis hall with a floor space of 40x63 m. The building is situated outside the urban area near the Moravičany municipality. The hall consists of 11 cross-links spaced by 6.3 m. The main load-bearing system consists of spatial arched trusses, purlins and lateral bracing that support the spatial rigidity of the construction. The calculations were made in compliance with the Czech technical norms ČSN EN.
