Torsional stress fixture design using a universal testing machine
Kučík, Jiří ; Jaroš, Jan (referee) ; Vaverka, Ondřej (advisor)
This thesis aims to design a fixture for static torque testing for the Shimadzu AGX-V2 series universal testing machine. The fixture enables the mechanical conversion of linear motion to rotational motion and the securing of samples. The design includes the method of attaching the fixture to the machine, the geometry of the tested samples, and their fixation. The introductory part of the thesis provides a brief overview of possible motion conversion methods, the standardization of torque tests, and examples of several torque testing machines. The conceptual part focuses on designing variants of the fixture. Two variants are proposed: the first based on the principle of gears and the second on the principle of cams. These are compared using the finite element method. Based on the results, the fixture with the gear mechanism is selected, capable of torquing both solid and structured samples at an assumed maximum torque of 250 Nm. In the construction part, the final design of the mechanism is carried out and then verified using the finite element method and analytical strength calculations.

Lifting roller table
Korytář, Jan ; Malášek, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
This thesis deals with the current lifting devices and conceptual design of the lifting roller table, which serves as a knot on the transport line. The table is used to transport 1000 kg EUR pallets, with a 200 mm height change required. The thesis contains a brief analysis of the lifting structures, the design of the roller track, the design and strength calculations of the scissor mechanism. It also includes assembly drawings, frame subassemblies, and workshop drawings.

Assembly Design of Ball-Joint Test Bench Hydraulic Unit
Novák, Jiří ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
The main object of this thesis is the proposal of fitting (setting) hydraulic cylinder into test equipment of ball-joints of company TRW-DAS Dačice a.s. The thesis includes a short review about testing ball-joint of above company and about liquid mechanisms. Also, there are analyzed demands for fitting (setting) hydraulic cylinder into testing equipment. In the main part of this thesis there is described my own constructive proposal with numeric calculations in proper software. In enclosure there are all analytical calculations with productive drawings and an assembly drawing.

Tesla Bladeless Turbine
Lokaj, Jakub ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The diploma thesis describes design of bladeless machine known as a Tesla turbine. The work is divided into theoretical part, practical part involving the design and experimental measurements of made bladeless turbine and a final assessment of thesis. The theoretical part deals with the basic design features of bladeless machines and their design modifications and flow in the nozzles. Furthermore there is a dedicated part of the dynamics of working fluid in the rotor of bladeless turbine represented by CFD modeling. The practical part includes the design and construction of parts of the turbine on a preliminary calculation using an analytical model of the flow in the turbine. The designed turbine components were checked for operational safety with structural calculations of shaft and disk impeller. The thesis was also performed experimental measuring of parameters of designed bladeless turbine. Measured values were compared with the analytical model which predicted turbine efficiency. In conclusion, besides to assessment, thesis also outlines possible proposals for further improvements of constructed bladeless turbine.
