Design of reciprocal module fixture for wear and friction measurements in tribometer
Zeman, Petr ; Šperka, Petr (referee) ; Dočkal, Kryštof (advisor)
The thesis deals with design of a clamping fixture for fastening surface samples for the reciprocating drive of the tribometer. The fixture is designed to compensate for shape deviations of the samples by tilting in two axes in a small range. The objective has been fulfilled, the tilting mechanism is achieved by rotating the spherical surface. The fixture is sufficiently rigid. It has been achieved of better user experience and repeatability of clamping. The paper contains an overview of commercially available clamping methods, their evaluation and description of the construction of the newly designed device, which simplifies the clamping of uniquely shaped samples for the reciprocating drive of the UMT TriboLab tribometer.

Modular Active Crossover Network - Laboratory Tool
Holínský, Jan ; Hanák, Pavel (referee) ; Balík, Miroslav (advisor)
This thesis is about design of active frequency crossovers and their implementation. The work analyses particular types of circuits used in active frequency crossovers, especially circuits used for laboratory device. Then the work describes design of printed circuit boards (PCB) for the designed circuits and construction of modules for the laboratory device, when the compatibility and modularity is important for all active frequency crossovers arts. These modules are made and testing its functions. In this thesis is disassembled final proposal laboratory device and laboratory device is realized. The design and measurement of the characteristics of active frequency crossovers and correction circuits is processed in the form of a laboratory tasks.

Design of clamping device for machining of manifold part
Foltýn, Jan ; Mazal, Pavel (referee) ; Svoboda, Petr (advisor)
This thesis deals with clamping fixtures. It aims to design an effective clamping solution for machining parts on a milling machine. The clamping solution was designed and then verified by a series of calculations. The main goal and partial objectives were fulfilled. The output is the design of fixture, which can clamp given part. Subsequently, based on the calculations it was decided to use four of these fixtures on one machining table. When calculating the appropriate variation of the fixture layout, an estimate of the time required for the operations performed by the machine operator was made. The thesis offers an overview of the materials used in the automotive industry. Furthermore, the study of clamps and clamping systems. It also touches the problem of optimizing manufacturing process and demand for ways to speed up the manufacturing process.
