Seismic resistance of the proposed pipeline route
Čapičík, Martin ; Nížňanský, Ľubomír (referee) ; Fuis, Vladimír (advisor)
The main goal of this thesis is seismic analysis and evaluation of given pipe line. In the first part we offer an overview of the modern seismic analysis methods utilized in nuclear power plants. In the following part we discuss the process of calculating of an assigned pipe line by means of equivalent static method in FEM Software Ansys 13. Based on the outcome we picked the least favourable load cases, which provided input data for determination of coefficients of safety and HCLPFMO34. Finally, the least favourable results are compared using the volume-solution and the analytical beam model in the Mathematica 8 software.

Seismic Analysis of The Pump 200-QHD
Čapičík, Martin ; Chlud, Michal (referee) ; Lošák, Petr (advisor)
The main goal of this thesis is dynamic analysis of shaft of booster pump QHD-200. In the beginning we offer basic equations generally used in dynamics and common/possible methods for their solution. Then we focus on specific problems connected with rotor dynamics and using simple Laval rotor we show their mathematical interpretation. Based on given load as accelerogram we create response spectrum in different ways (using different methods) and compare their CPU time demand. In the next part we make three finite element models of different physical level. We perform modal analysis and comparison of eigen frequencies, mode shapes. In following chapter transient analysis was performed on all models. As load we use accelerogram. We evaluate translations in particular positions of model. After that, we decide whether or not gap between impeller and stator case will be erased. Finally we make assessment of force acting upon bearings.
