Vibrodiagnostics of rotating machines
Honc, Lukáš ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
This bachelor's thesis deals with vibrodiagnostics of rotating machines focusing on unbalance of rigid shafts. The purpose of the thesis has been designing, realization and practical verifying of measurement algorithm and program for balancing of rigid shafts in one and two planes. The prerequisite has been to use hardware of National Instruments company and software LabVIEW. In first chapters, reader will read about characteristics of vibrations measured on rotating machines, their sources and analysis. Next chapters focus on measurement and analysis of data, balancing and its realization.

Voltage quality index for distribution systems voltage quality benchmarking
Hausner, Josef ; Topolánek, David (referee) ; Drápela, Jiří (advisor)
This Master’s thesis deals with design of a new method for voltage quality benchmarking using voltage quality index. This index should determinate total voltage quality in the power grid and compare voltage quality in different places. There is design of several algorithms which value measured parameters in this thesis. The best suitable algorithm is selected. Program for this algorithm was compiled in GUI Matlab. The algorithm is verified by using measured parameters in this program. The last part of this thesis is focused on possible usage of created algorithm.

Balancing Rotors of Steam Turbines
Filip, Patrik ; Šnajdárek, Ladislav (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is a technical research dealing with issues of balancing turbine rotors and generally describing international standarts commonly used for balancing rotors. The first part is about unbalance in general context. The next part classifies types of rotors, standarts for balancing rotors and balancing methods. Then there is a description of a balancing device. The last part of this thesis includes a step by step process of balancing a specific rotor.

Turbocharger Rotor Balancing
Šárovec, Marek ; Zubík, Martin (referee) ; Knotek, Jiří (advisor)
This bachelor’s thesis is specialized search dealing with issues of turbocharger rotor balancing. This work is divided into three main parts. First part deals with history of turbocharger and basics of turbocharger construction. Second part talks about types of unbalance and how to balance. Also, there is description of balancing machines. Last part depends on previous part because there is application of balancing on automotive turbocharger.
