Crank mechanism of in-line three-cylinder diesel engine
Cetkovský, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective bachelor’s thesis, which will be achived is, for scheduled elementary geometric, thermodynamic and operation parameters cylindrical unit of in-line three-cylinder diesel engine, perform calculation of thermodynamic cycle, design elementary dimensions of piston group and for schedule operation modes perform strength check of connecting-rod eye. Consequently rating value compare with value of real true diesel engine. In introduction is explained basic principle of diesel engine and their design concept. The bachelor’s thesis is consisted of description of calculation and supplement, where the calculation is done. The calculation is accomplished in three parts. Thermodynamic cycle is solved in the first part. Forces acting on piston group are solved in the second part and strength calculation and check of connecting-rod eye is solved in the third part. The end is focused on evaluation of calculation and recent solution of diesel engine.

Powertrain of experimental single-cylinder spark ignition engine
Číp, Tomáš ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is, for noted geometric, thermodynamic and operation parameters cylindrical unit of experimental single-cylinder spark ignition engine, perform calculation of thermodynamic cycle, project basic proportion of piston group and for noted operation modes perform strength check of connecting-rod eye. In preamble is stated basic use of spark -ignition engines, their operation principle and basic fisson. The bachelor’s thesis is consists from of calculation, which is continuously described.The calculation is consists from four parts. The first part is calculation of thermodynamic cycle, in the second part are calculated concept piston group, in next part are calculated forces reacting to piston group and fourth part is strength calculation and check of connecting-rod eye. In the last part is results evaluation of calculation.

Structure Design of Exhibition Pavilion
Ruček, Martin ; Šmak, Milan (referee) ; Hron, Lukáš (advisor)
Concern of my thesis is to design the main load carrying structure of an exhibiton pavilion. The pavilion itself has circle shaped footprint, 55 m in diameter. Height of the building is then 15 m. The main structure consists of planar truss elements with generally curved upper and lower chords. The web of main truss element is designed as a perforated steel wall. Structural analysis and dimension design of main truss element is realised via axis model with rigid nodes, and verified on an accurate numerical model of a truss with web modelled as a perforated steel wall. Building is designed to be situated at exhibition area of Olomouc city. Design involves all the critical cross sections, and also selected mounting joints.
