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.

Static design of the structure composed of combination of steel and structural glass
Potůčková, Simona ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The objective of the bachelor thesis is to design the load-bearing construction system and its cladding made of a combination of steel and structural glass and to verify its sufficient resistance. The object has rectangular floor plan with dimensions of 7,5x10,5 m and and its total height is 24,5 m. The building is located at the suburban area of the city Ostrava, precisely Ostrava Poruba. The construction is composed of a ground floor and six upper floors. The main load-bearing system consists of steel frame formed by six tubular columns connected beams and sway bracings ensuring the spatial rigidity of the structure. The object was designed according to currently valid standards using ULS and SLS verification.

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.

Multifuntional Sport Hall
Škatula, Václav ; Pilgr,, Milan (referee) ; Barnat, Jan (advisor)
The bachelor thesis presents a project of a load bearing structure of a multifunction hall that has a rectangular ground plan and also deals with the assessment of the project. The object is situated in the urban area of Ostrava. The task provides two versions of design. The first version consists of ten traverse joining beams witch are distanced five meters from each other. The second version consists of six traverse joining beams witch are distanced nine meters from each other. The thesis focuses on the load pressure of the steel construction, the main emphasis being placed on the single structural components and assembling components. The calculation meet the standards of ČSN EN.

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.

Hangar
Škatula, Václav ; Bajer, Miroslav (referee) ; Sýkora, Karel (advisor)
The final thesis is focused on a project of a load bearing structure of a aircraft maintenance hangar that has a rectangular ground plan 60,0x120,0 m and includes suspended mobile hoist of loading capacity 5,0t. The object is situated in the airport area of Ostrava Mošnov. The task provides two versions of design. The first version consists of eleven traverse joining beams witch are distanced twelve meters from each other. The second version consists of thirteen traverse joining beams witch are distanced ten meters from each other. The thesis focuses on the load pressure of the steel construction, the main emphasis being placed on the single structural components and assembling components. The calculation meet the standards of ČSN EN.

Multipurpose barnbuilding
Janírek, Karel ; Bukovská, Pavla (referee) ; Barnat, Jan (advisor)
The content of the bachelor thesis is a proposal and evaluation of the timber construction of multipurpose barnbuilding. It is used for breeding and presentation of animals, especially horses. The building is situated outside the urban area near the Jeseník municipality. Plan dimensions of the hall are 25,0 x 44,0 m. Height is 12,5 m. It is a curved construction of glued laminated timber. The hall is made of 12 cross – binding – triple joint arches in the shape of circle. Individual cross – binding are distanced 4,0 m. The stability of the whole construction is toughened by 3 areas of bracing. Plan dimensions of the stable are 7,0 x 64,0 m. Height is 4,515 m. Construction of the stable consist set of 17 frames of glued laminated timber, distanced 4,0 m. The stability of the whole construction is toughened by 2 areas of bracing. The calculations were made in compliance with the Czech technical norms ČSN EN.

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.
