Testing of the Common-rail pressure regulation valve by ADwin device
Šoulák, Vojtěch ; Svída, David (referee) ; Kučera, Pavel (advisor)
Tato diplomová práce se zabývá rozšířením testovacích možností vývojové stanice pomocí zařízení ADwin. Hlavní částí diplomové práce je navržení přídavného okruhu testovací stanice a naprogramování testu pro tlakový regulační ventil. V další část se diplomová práce zabývá předpokladem stavu komponent regulačního ventilu po testování. Při porovnání tohoto předpokládaného stavu a reálném stavu po testování je ověřeno správné naprogramování testu a správná funkce nově navrženého okruhu.

Gas sensors, their construction and testing
Pytlíček, Zdeněk ; Boušek, Jaroslav (referee) ; Prášek, Jan (advisor)
This work deals with branch of gas sensors, their construction and methodology of testing. The general aim is a design and implementation of a station for simple testing of conduction gas sensors. The whole station is conceived as virtual measuring apparatus, operated by PC in LabView environment. The station enables mixing of any two gases at concentration demanded and measuring of the basic conduction characteristics of the thick-film and thin-film gas sensors. The central communication interface and modular conception enable easy expansion of possibilities of the whole apparatus in the future. It is possible to measure up to eight gas sensors split into two TO-12 packages simultaneously.

Oxygen detection using gas sensor
Jelínek, Tomáš ; Pytlíček, Zdeněk (referee) ; Prášek, Jan (advisor)
In this master´s thesis various types of gas sensors, their characteristics, principle, active layer and structure are described. This work is focused on semiconductor gas sensors. In the experimental part gas test station is used to measure the main characteristic of commercial sensor Figaro TGS 822 and own SnO2 gas sensors and reaction to oxygen. Both sensors and measurement results are compared with each other.

Physical axle model for dynamic tests
Bělunek, Matěj ; Dočkal, Aleš (referee) ; Mazůrek, Ivan (advisor)
The aim of this thesis is the design of a physical axle test station, along with a virtual dynamic model, with the purpose of vehicle suspension tests. The axle, or half-car, model is the answer to the inaccuracies of the most widely utilized suspension model, and the high cost of the full vehicle testing. The motivation for the new test station and its virtual model is the prospect of accurate, quick and effortless testing and optimization of the vehicle suspension characteristics. The existing solutions in most cases substitute actual suspension elements (axle) and wheels with auxiliary parts leading to a departure from reality. The design of the new test station is based on the analysis of current physical model solutions and in accordance with set requirements. The tester substitutes the vehicle Škoda Fabia I Hatchback and utilizes its actual rear axle including suspension elements. The assembled rig, or rather its functionality, is successfully experimentally verified. The created virtual dynamic model, using ADAMS software, is identified against the designed test station, while the obtained simulation results are compared with the experiment data. Meeting the experiment predictions and virtual model results validates the tester’s ability to sufficiently reflect real car suspension behaviour and it is ready for further vehicle spring and damping properties testing.
