Modal analysis of the swirl turbine runner
Valo, Lukáš ; Fic, Miloslav (referee) ; Čupr, Pavel (advisor)
The bachelor’s thesis deals with modal analysis of the swirl turbine runner. The main aim was to determine natural frequencies and mode shapes of the turbine runner. Both detailed and simplified models of geometry of the turbine runner were analysed for two types of boundary conditions. The ANSYS program was used to carry out numerical simulations. Experimental measurement was realised to verify and to compare results of calculations.

Flat Plates Vibrations
Zajac, Roman ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The diploma thesis is focused on vibration of the planar plates. It includes the computational and experimental approaches used to determine the mode shapes and frequencies (eigenvalues) of planar plates. This paper compares the analytical, numerical and experimental results of the modal analysis specifically the free-standing rectangular planar plate. The work also encompasses forced oscillation with harmonious excitement as a continuation of the obtained results from modal analysis.
