Strain measurement system
Novotný, Jan ; Fedra, Zbyněk (referee) ; Štohanzl, Milan (advisor)
The batchelor thesis is focused on the design of strain measurement system using a metal resistance strain gages. Measured analog quantity is converted to digital form and sent to microcontroller, where the quantity is adapted and then display. The first part of project looks into genesis of different types of mechanical stresses, principles of resistance strain gages, the types of measurement bridges, theory of analog-to-digital conversion and short description of used microcontroller and liquid-crystal display. There are wiring diagram of the system and printed circuit boards designed in the second part of project. System can be also calibrated and driven by PC using Universal Asynchronous Communication Interface. System is physical realized, its functions are checked and there is subscribed driving of the system. Finally other alternatives of improving properties of the system are analyzed due to posibility of using of the system in practical aplications.
Design of device for measurement of aerodynamic forces and moments in wind tunnel
Brožek, Petr ; Matějů, Jiří (referee) ; Lajza, Ondřej (advisor)
The masters thesis is focused on design of the device for measurement of the aerodynamic forces and moments acting on radiators mounted in the wind tunnel test section. The thesis also includes the analysis of the aerodynamic drag which is produced by radiators and the LabView application software development.
Laboratory exercises using LabView measurement tool
Černocký, Petr ; Šmirg, Ondřej (referee) ; Rampl, Ivan (advisor)
This bachelor thesis deal with weight measuring using the deformation elements and LabVIEW measurement tool. The target of thesis is to design and realize two laboratory exercises using Wheatstone bridge for transfer weight to volts. Secondary target is design and construct electronic circuit for processing analog signals, which can be processed in data acquisition device.
