Design of computational algorithm for using of hollowed shaft in electric machine
Tobiáš, Jan ; Hadaš, Zdeněk (referee) ; Vlach, Radek (advisor)
The aim of this work is to develop the possibility of usage the hollow shafts in electric machines. The first part focus on explanation theory of mechanic, which is connected with loading of the shaft. Specifically are explained the methods of computation deformation and normal stress. Next is mentioned the theory of gyroscope and described its consequence. After that is explained problematique of critical speeds. In the following part is described process of solving the shaft loading according the previous analytic formulas. These formulas are formulated to be able to reflect the shaft loading depending on value of inner diameter as property. Practical part focus on creating the calculator for usage the hollow shaft in electric machines. In this chapter is described how the calculator works and how to controll it by user. In the last part are shown calculated results and their analysis. In the summary is mentioned possible usage of the results and ideas for improvements.

Analysis of vertical synchronous generator modal properties
Kornherr, Milan ; Donát, Martin (referee) ; Dušek, Daniel (advisor)
This Master´s thesis deals with the analysis of modal characteristics of the vertical synchronous generator. The goal of this work is to determine influence of individual parts of the generator on modal characteristics. Another part of this thesis contains analysis of different variants for storaging the generator and also structural modifications, which lead to the improvement of the modal properties. For modelation was used cumputional modeling in ANSYS.
