Wheel Alignment for race cars
Vanda, Marek ; Hejtmánek, Petr (referee) ; Porteš, Petr (advisor)
This diploma thesis deals with the design of device for measuring wheel alignment and set- up of race car chassis. The real prototype of measuring device based on previous theoretical design has been made. The measuring procedure is mentioned as well. Another part is focused on factors affecting accuracy of measurement. The last part contains evaluation and discussion of gained results based on several measurements that have been done with prototype of measuring device.

Design of a device for measuring the center of gravity height of road vehicles
Hanych, Jaroslav ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This master's thesis deals with problems connected with measuring vehicle centre of gravity height. The research part summarizes generally known methods of measuring vehicle centre of gravity and moments of inertia. Essential part of this thesis is the design of a device for measuring the centre of gravity height of a road vehicle on a principle of measuring a period of oscillation. The height position of the platform of the device is adjustable through hydraulic cylinders. A stress-strain analysis of the design was executed through a combination of analytical methods and a finite element method. The process of measurement was described and an equation for determination of centre of gravity height was deduced. Error of measurement was estimated based on the knowledge of partial errors of measured values.

Center of Gravity Measurements of Bicycles
Burda, Ondřej ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
The first part of the thesis The measurement of the location of centre of gravity of bicycles is firstly about history and division of bicycles, about the legislation in the Czech Republic concerning the cyclists, about the analysis of accidents of cyclists and lastly about the analysis of the method of the measurement of the location of centre of gravity. The second part of the thesis describes the procedure of calculation of the location of centre of gravity in the chosen incline method and the proposal of measure apparatus. The third part of the thesis occupies with the measurement and processing of concrete values for chosen sample of cyclists on the bicycles which are selected in the way that the results of the location of centre of gravity in the final part of the thesis are compared with the respect to their application during the expert opinion.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.
