Universal Inspection and Measuring Station
Brýdl, Adam ; Bradáč, František (referee) ; Knoflíček, Radek (advisor)
The task of this thesis is the design and construction of semi-automatic control and measuring station. The station is designed for testing the presence and measurement of the correct position of light guides and seals in the connector. Station contains a tool for testing the blinding of connectors. The design and construction of a semi-automatic control and measuring station is necessary using several types of sensors and sliding linear axes controlled by servo drives. The assignment of the thesis is solved in cooperation with the company Mechatronic Design & Solutions s.r.o. in Brno.

Analytical calculations of flange joints
Polišenská, Anna ; Chalupa, Aleš (referee) ; Hůlka, Jiří (advisor)
This Master’s thesis deals with flange joints. A suitably designed flange joint (FJ) construction and installation is necessary to ensure the reliability of piping systems and machinery where these joints are used. The thesis describes the procedures of their design and assessment in terms of tightness, strength and durability. It focuses on the stiffness calculation of all components of FJ – primarily the stiffness of flanges, bolts and seals. The main part of the work was to create a computational program by using the Python language to determine the appropriate preload force in the bolts. The program uses the procedures described in the ČSN EN 1591-1 standard. The thesis describes computational algorithms of this program, verification of the program and its use in the assessment of FJ on a specific technical work – pressure vessel with adjacent piping. Verification was performed by comparing the acting force to the seals obtained from the computational program and the stress-strain analysis using the finite element method (FEM), where the load model in this stress-strain analysis included the preload force obtained from the computational program. The application of the pressure vessel computational program consisted in determining the preload forces for all FJs of this assembly. The last part describes the assessment of the most loaded FJ. Again, stress-strain state was evaluated using FEM and FJ was assessed for tightness, strength and durability using the NTD A.S.I. standard.

Indoor swimming pool - concrete tank construction
Pőthe, Péter ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
The aim of the diploma thesis was to design reinforced concrete construction of the indoor swimming pool and ensure impermeability of the construction, to ensure behavior as concrete tank construction. Static analysis was done by using program Dlubal RFEM 5.12, where interaction of subsoil with construction was taken into account. Slabs around the swimming pool area were divided into expansion section because of temperature changes from glass façade an after that the sealing of expansion gap was solved. Construction system under the swimming was designed and was tested the behavior of walls and slabs. Analysis was done also to considerate of hydration heat. The drawing was done by software CADKON RCD.

Comparison of flange connections design
Hrbáček, Jan ; Dohnal, Miloslav (referee) ; Buzík, Jiří (advisor)
Flange connections are type of connections frequently used in industry. There are hight claims for their dimensioning, strength and tightness. The proper and exact design can be made by calculation or by choice of standardized components (flanges, bolts, nuts etc.) accordig to requirements established by standart. This Bachelor´s thesis occupies itself with qualitative comparison of proposals for the strength design of flanged conections according to ČSN EN 13445, AD 2000 Merkblatt and ASME Code standarts. The programming language called Python is used in this Bachelor´s thesis.

Design of Experimental One-cylinder Engine with Floating Liner
Svoboda, Radovan ; Svída, David (referee) ; Novotný, Pavel (advisor)
The aim of this master`s thesis was to design a single-cylinder test engine for measuring of the friction forces between the piston group and the cylinder liner. Main engine parameters are based on the common production engine. A floating liner device was chosen for a friction forces measurement. It was necessary to solve an attachment and sealing of the floating liner. Stress-strain analysis of the floating liner has been done. Next step was to re-design a production crankshaft also with a connected balancing devices for single-cylinder engine. Powertrain was seated in a completely new units. Finally the engine was completed and mounted on a stand.
