Odezva atypického vertikálního rotoru vodní turbíny na buzení nevývažkem oběžného kola a nevývažkem rotoru generátoru / Response of atypical vertical rotor of a water turbine to excitation by impeller imbalance and generator rotor imbalanceSitte, David January 2021 (has links)
This master’s thesis deals with the dynamic behaviour of vertical Francis turbine, which is atypical its shaft length. In the first part of thesis, there is theoretic research of water turbine, which is followed by derivation of equations for the Stodola rotor. The second part deals with the creation of the turbine shaft in 1D and 3D. A modal analysis was performed in the ANSYS Workbench software, based on which the Campbell diagram is created and it was determined the critical speed. And the harmonic analysis from which was determined the forces response in radial bearings, amplitude of deviation in radial direction in the turbine impeller and the generator and the axial displacement located in turbine impeller and axial bearing. 1D and 3D solutions were compared between themselves.
