Simulation of the Laval rotor supported by nonlinear bearings
Krček, Aleš ; Hrstka, Miroslav (referee) ; Lošák, Petr (advisor)
The presented diploma thesis deals with simulation of Laval rotor supported by nonlinear bearings. The first part of thesis deals with research, which is focused on description of Laval rotor and motion equations for case of rigid and flexible rotor, also on description and modeling of hydrodynamic and magnetic bearing, which is considered in thesis. The second part of thesis deals with simulation of rotor for different approaches to modeling hydrodynamic and magnetic bearings. Using simulations performer in time domain, the dynamic behavior of Laval rotor is evaluated and compared. Simulations are performer in MATLAB.

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.
