Testing facilities for burner testing
Sobočík, Robert ; Hájek, Zdeněk (referee) ; Bělohradský, Petr (advisor)
This Bachelor’s thesis is focused on testing facilities intended for burner testing. It deals with a thorough research of accessible material including specialist technical literature and relevant websites in order to gather any available information on current burners and monitor present situation in the market, as well as to provide new information on burner testing facilities and collecting, processing and evaluating the data gained in testing process in Czech and foreign companies.

Test bend for vehicle air-conditioning testing
Andrýs, Jan ; Hejčík, Jiří (referee) ; Štětina, Josef (advisor)
The aim of this work was to design test bend for vehicle air-conditioning. This test bend should simulate interior of the car and the engine compartment. Electric motor is used to drive compressor in test bend. Air supplied to test bend is modified to extreme conditions and the volume of supplied air is the same as the car drove at 50 km/h. Main frame of test bend is made from aluminium profiles manufactured by Bosch Rexroth, which provides great modularity. Walls are made from insulated panels by ELCOM System, they have very good insulation and are strong so additional equipment can be installed inside. Construction design was made is SolidWorks with 3D models of test bend as output. Air-conditong parts which were used as samples are originally from Skoda Octavia II. For this vehicle were made calculations of heat loads. In conclusion is simple testing example for this test bend and although there are some examples for future measuring.

Design of laboratory stand for temperature measurement
Matějů, Jiří ; Horský, Jaroslav (referee) ; Raudenský, Miroslav (advisor)
This Bachelor’s thesis solves design of a laboratory stand for temperature measurements. The stand is able to accelerate a steel sample of maximal weight 20 kg from the height of 7m to the speed of maximum 10 m/s. During a duty cycle of the stand the sample is accelerated on the length of 4 m, the constant speed is kept on the length of 2 m, on the length of 1 m the sample is stopped and then it’s lifted to a position for accelerating. During the constant speed the sample is cooled by water nozzles and there is measured temperature curve in the sample. The acceleration and constant speed is regulated by asynchronous servo motor with servo-driver. The stopping of sample is done by external mechanical braking system. The thesis is focused on selection of design solution, basic dynamic calculation and selection of individual components of stand.

Design of experimental device for durability testing of bearings
Frejlich, Tomáš ; Dvořák, Antonín (referee) ; Svoboda, Petr (advisor)
Diploma thesis deals with the structural design and subsequent implementation of a functional prototype of an experimental device for durability testing of bearings. The first part of the thesis deals with an overview of the current state of knowledge and summarizes information about testing the durability of bearings. In the next part follows the design, selection and analysis of the optimal design variants. The last part deals with the verification of the functionality of the prototype bearing life testing and evaluation of data measured during testing.

Rig for Testing Suspension Components
Nedoma, David ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
Development of car suspensions needs optimalisation of comfort, durability over external conditions, reduction of un-sprung mass, car handling. This requirements often need contradictory solutions and during solving it is necessary to take compromises. Verification of durability of car suspension is better while developing the whole car. Therefore, many solutions of car suspension test rigs are created. This thesis brings summary of existing solutions and their construction. This thesis brings its own solution of the suspended test equipment, strength calculations of main components. You can find here procedure of testing components on this test rig as well. Written ideas for future development of this rig are mentioned in last chapter

Burner testing
Rychter, Aleš ; Hájek, Zdeněk (referee) ; Bělohradský, Petr (advisor)
Bachelor thesis deals with testing of burners used in industrial applications. Overall is work divided into two main parts in which the first one is focused on basic classification of burners according to mixing type, fuel type and air supply system. The Second part of work is then focused on the burner tests. It describes types of tests and test environments in which the combustion tests can be carried out. In terms of tests, it is then necessary to make some important decisions, including the choices of testing fuel, combustion chamber and oxidizer, which have impact on the result. The preparation of tests also includes the developing of test procedure in which it is necessary to include the requirements of specific tests. The tests have to be carried out according to the relevant technical standards. After the realization of every test the evaluation of measured data has to be done and the test report summarizing the results of the test has to be issued. Since during the tests a number of process variables is measured like emissions, temperatures, pressures, flow rates, etc., the necessary instrumentation is described as well.

Measurement of vehicle suspension bushing characteristics
Kopecký, Petr ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
This master’s thesis deals with the measurement of static characteristics of wheel suspension bushings. It includes a structural design of the test device and drawings according to which the device was manufactured. The device has several variations for different stresses and is applicable with possible modifications to various bushings including the ones that do not have common axes. The measurement procedure, the results of the measurements of the static characteristics and their analysis and comparison with the finite element method calculations are also given. The measured characteristics were then added to the model of the axle for multibody simulations.
