Training system for clibmers
Polach, Pavel ; Sekora, Jiří (referee) ; Bubník, Karel (advisor)
The purpose of this diploma thesis was design and realisation of measuring system, enabling measuring forces between climber´s feet and holds on the climbing wall and using this measu-red values during a training of sport climber. In this thesis there are discovered possibilities about constructing this system and determina-ted basic requirements of measuring. There are also stated principles of application the strain gauges for measuring the tension. Descriptions of developping specific sensors, hardware interface and PC application are also part of this thesis. Constructed system was used for mea-suring climbers and values were analysed by using the application.

System for evaluation of upsetting test
Janečka, Dominik ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The thesis deals with the proposal of measurement system for evaluating upsetting test. The variables for evaluating the test are obtained by using sensors of measuring devices. The necessary magnitudes are force, track and temperature. For this purpose they were used sensors HBM R6C, HBM W50 and thermocouple type K. The sensor signals are amplified by measuring modules Dewetron and transferred to a PC by measuring card NI USB-6009. There are further processed by evaluation program DEWESoft 6.5. In a final part are performed a verification measurements to assess system function.

Experimental load definition
Dratva, Jakub ; Horák, Marek (referee) ; Jebáček, Ivo (advisor)
The thesis is focused on experimental load definition of an aircraft. Especially is measured bending moment is measured on wing during the flight. The thesis includes theoretical basis for strain gauge measurements and procedure of statistic evaluation. For each of flight maneuvers, there are theoretical wing loads calculated and then the values are compared. The end of the thesis shows proposals for improvement of used method of flight possible repeated measurement.

Measuring the forces acting between the wheel and the road
Gellner, Pavel ; Tobiáš, Martin (referee) ; Porteš, Petr (advisor)
The diploma thesis is focused on the measurement of forces acting between the tire and the road. There is an outline of tire and tire models problematic in the opening part. In the following part, the rear right suspension of the formula student car was mounted with strain gauges and the data logging system was described. There is also a multi-body model of the rear axle created in Adams/Car and SAMS software, that is able to calculate forces acting between the tire and the road, taking the measured forces in the suspension, rocker position, and throttle position into consideration. After a series of calibrations and verification measurements, the measurement on the test track was made, with data analysis focused on forces acting between the tire and the road.

Design and construction of the task to the subject PPI
Král, Jiří ; Krejčí, Petr (referee) ; Návrat, Tomáš (advisor)
The bachelor thesis deals with creating of computational model for definition of tensity and deformations of bars system. Then the physical model is made according to the theoretical model. This physical model is used for educational purposes. Next step is measurement of stress and deformation of bars. The final part is focused on eventual variations between theoretical and real model.
