Engineering design of the vehicle suspension rocker
Poláček, Vojtěch ; Ramík, Pavel (referee) ; Bradávka, Marek (advisor)
Diploma thesis deals with the design and stress analysis of the rocker suspension for an autocross car. The research describes some real cases of using suspension with pushrod and rocker in motorsport. Subsequently, the work deals with the design of the wheel bump/rebound limiting stops and bump/rebound measuring. The challenge is to design a component shape, size and select fit of a rocker with an emphasis on low weight whilst maintaining sufficient strength and rigidity. The design study include stress analysis which leads to optimize the final shape.

Study of fatigue life of roller bearings type 6204 -2Z
Poláček, Vojtěch ; Svoboda, Petr (referee) ; Klapka, Milan (advisor)
This bachelor thesis deals with the basic description of produced by fatigue failure of ball bearings. In the paper there is a description of basic diagnostic methods of machine parts. Following there is a study of vibration, their recording and the evaluation concerning bearing lifetime. The aim of the experimental part of the paper is to check the functionality and suitability od the VDT2000 analyzer and VDT Control Center software, both made by company VidiTech, s.r.o. together with the SA67 laboratory experimental stations owned by the Department of Design at Faculty of Mechanical Engineering, which were used for examining the 6204-2Z bearings. The aim of the lifespan exam is to confirm the reliability of the bearing failure warning by the analyzer and to assess the ability to record the first stages of bearing damage.

Apartment building
Poláček, Vojtěch ; Svoboda, David (referee) ; Čuprová, Danuše (advisor)
The subject of the bachelor’s thesis is project documentation of new appartment building in Oblekovice on street Šatovská, the part of city Znojmo. The proposed object is located in an existing suburban developement. It is a three-storey apartment building, partly witch a basement with loggias, a terrace and a flat vegetated roof. In basement we can find cellar cubicles for each apartment unit. On the 1st floor there are two apartment units categories 3+1 and technical facilities, on the 2nd floor are three apartment units, two of them categories 3+1 a one of them 1+1 and on the 3rd floor are two apartment units categories 4+kk. Designed appartment building is built with modern technologies, load-bearing walls of aboveground part of the building are made from clay blocks in Profi and AKU variants. Underground part of the building is made from structural formwork with concrete and rod reinforcement. Building’s foundation will be made of cast-in-place concrete strip footing with reinforced concrete floor slab. The load-bearing part of the ceiling structure consists of semiassembled ceilings of the Miako type. Staircase is also made as reinforced concrete slab with stair steps made of concrete.

The idea of Czech national theatre in Brno - study of architecture, society and politics
Poláček, Vojtěch ; Christov, Petr (advisor) ; Just, Vladimír (referee)
The subject of this dissertation is the history of Czech national theatre in Brno. Primary goal is not an artistic development of the stage, but the wider consequences of its existence (mainly political, social and economical). During the chronological explanation the work focuses on periods and events in which these consequences are most evident (new theatre building architectonical competitions) or most dynamically changing (political or administrative overturns). This work has two main issues. In a first place, it proofs that whole idea of Czech national theatre in Brno was not fully understood either by the public, or by the representatives of this institution. It was and is rather a good marketing label, then wellconsidered ideological concept (in comparison to National theatre in Prague). Second big issue is a confirmation of Czech-German discords as determining power in Brno's social life before year 1945. Tension between two national groups in town was on one hand causing discomforting atmosphere of mutual seditious campaigns, but on the other hand, it was also a base for beneficial competitiveness. And this can be clearly proofed by formation and further development of Czech national theatre in Brno. The main sources of this work are archive materials of Czech national theatre syndicate in Brno...
