Analysis of railway motor-generator set
Mánek, Petr ; Hadaš, Zdeněk (referee) ; Ondrůšek, Čestmír (advisor)
This work is focused on using of modal analysis in power electrical engineering. The first part of the work explains the term of CAD systems and provides their basic classification. The next section of this thesis describes procedure for creating models in Autodesk Inventor 2012. There is shown creation sketching, 3D components, assemblies and possibility of presenting the models. Next part of this thesis describes the finite element method and the program ANSYS Workbench. In the next part of this thesis is shown sample of calculation of modal analysis in the program ANSYS Workbench. There is a description of modal analysis, synchronous machines, the process of calculating of modal analysis and evaluation of the results. The last section of this thesis describes creation of animation of the railway generator set in the program Inventor Studio.

Utilization of adaptive CAD systems at virtual model creation of electrical motors
Sedláčková, Petra ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
Thermal analysis of electric machine is one of the key steps in design procedure. Traditionally, thermal calculations are done by analytical method, mostly based on equivalent electrical circuit, where thermal quantities are replaced by equivalent electrical quantities. These methods employ so-called electro thermal analogy. Different approach is to use Finite Element Method, which is the main goal of this thesis. First part of the thesis is devoted to description of CAD system Autodesk Inventor, which is modern parametric CAD for modelling of virtual prototypes. This system is then used for creation of three dimensional model of brushless DC machine. Second part is focused on thermal calculations in Ansys Workbench environment. Model of brushless DC machine created in Inventor is transferred into Ansys Workbench and thermal analysis is carried out.

Application of modern technologies for manufacturing models of hedgehog in the cage puzzle
Dratva, Jakub ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The objective of the bachelor thesis is the designing and manufacturing of so called a hedgehog in the cage puzzle model. Individual moulds and dimensions of puzzle were designed in the 3D parametric software Autodesk Inventor. The puzzle model was manufactured by Fused Deposition Modeling method using 3D printer uPrint. The part of the project was manufacturing the silicone mould that will be used to cast the required number of the cage made of commercially available material (plastic). The work was finished with technical and economic evaluation with the subsequent analysis and overall assessment of applied technology.

The Design and the Possible Practical Application of a Cooking Pot Handle 3D Model
Bezděk, Adam ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The target of this bachelor thesis is designing and producing of a 3D model cooking pot handle with use of the modern 3D printing technologies. The virtual model of the cooking pot handle was produced with parametric program Autodesk Inventor and then printed by the Dimension uPrint 3D printer, which uses the Fused Deposition Modeling additive technology. The silicone mold was produced by using the printed master model. Then the model was molded from the two component plastic material into the silicone mold. Conclusion of this work contains technical-economic evaluation, where are both methods of producing the model compared.
